On this reference guide, you will find a listing of most of the folding knives that have been manufactured by Case. They are listed in order of the knife's factory pattern number. The listings are composed of a picture, a brief descriptions, and various names that each knife goes by.

Please note that most of the names that collectors use to describe certain pattern numbers vary at times. I have tried to include all of the names used by most collectors. Many patterns share the same name as another. Others have their own unique name that is universally known and used by all collectors.

Make sure to stop by our store when you get done researching & shop for W.R. Case pocket knives to add some of the many great pattern variations to your collection of folding Case pocket knives!


As you use this reference, keep in mind that most collectors categorize pocket knives into three categories. Jack Knives, Pen Knives, and Multi-bladed knives. Jack knives are usually single ended, meaning that their blades are hinged on the same side. Some larger double ended knives fall into this category as well. Pen knives are generally lighter weight double ended knives that have blades that open on both sides. Multi-bladed knives are those with more than two blades.


Pattern # 00

This number has been used on three distinct folding knife patterns.

Case XX (1940-64) Mellon Tester KnifeThe most recent 00 pattern is a 5 1/2" jack knife known as a melon tester, citrus tester, or sausage tester. They were produced with either one or two blades. The one bladed version has a long spear blade, and the two blade version has two spear blades that open on the same end. A few have a serrated master blade. These were specially made for a few customers and are generally quite a bit more valuable. The citrus tester was introduced in the late 50's and was discontinued after the 1975 production year. Case only made them with white composite handles and stainless steel blades.

* Case manufactured a 4 5/8" Jack knife with the pattern number 00 sometime prior to 1940. They are clasp style Jackknives that have a single clip blade and no left side bolster.

*Case also produced a 4" jack knife with the pattern number 00 sometime prior to 1940. These are double-bladed knives that are known as copperhead trappers. I believe they always have a clip master blade and a spey secondary.


Pattern # 01

Case XX 6201 R Pen KnifeThe 01 pattern is a 2 5/8" two bladed pen knife known as a senator pen or equal end pen. The master blade will usually be a spear blade, and the other is almost always a pen or file blade. Some of these knives have been manufactured with a bail, and several have been made with tip bolsters. The 01 pattern dates back to the Case Brothers era (1896 - 1915). It was later discontinued for a while after 1974 and reintroduced in 1980. The knives have been manufactured with yellow composite (3201), bone (6201), imitation pearl (9201), and cracked ice (9201).

Pattern # 02

Case 6202 Barehead Jack KnifeThis pattern is a 3 3/8" jack knife that most collectors call a regular or bare-head jack knife. They have two blades. The master is usually a clip, and the secondary a pen. Some have a one armed man a.k.a. razor master blade with a pen secondary. The pattern was introduced prior to 1915, and discontinued in the late seventies. It can be found with black composite, rough black, green bone, bone, and delrin handles. After 1970, delrin was the only material used. Some were manufactured with an easy open feature.


Pattern # 03

Case manufactured a 03 pattern between 1905 and 1914 that is known by many collectors as a half canoe. They are 3 5/8" jack knives that have canoe style bolsters on the left, and pinched bolsters on the right. They have two blades that extend from the same side.

Case's most recent 03 pattern is a budding / grafting knife.


Pattern # 04

Case's most recent 04 pattern knife is a 3 3/8" Jack knife that is known as a budding or grafting knife. They have a single spey blade and do not have a left side bolster. Case introduced the knife sometime prior to1940 and discontinued it in the early 1940s. As far as I know, they were only manufactured with bone handles (6104).


Pattern # 05

Case XX 6205 R One Arm Man Barlow KnifeThis pattern is a two bladed 3 3/4" barlow style jack knife. They are often known as a one arm man or one armed bandit knives. Most recent 05 patterns usually have a razor master blade, but in the past, they have also been manufactured with clip or spear master blades. The second blade is always a pen blade as far as I know. When the knife has a razor style blade, it most often takes on the name one arm man. This name was given to the knife because the design of the blade has a tip that sticks out. This allows for the knife to be opened with one hand by snagging the point on a pant leg or other object. When this pattern has this style of blade, the pattern number (when there is one) is normally followed by an R, or RAZ. When the knife has a clip master blade, the pattern number may be followed with a 1/2. The 05 patterns were introduced prior to 1940. Starting sometime before 1965, the knife was only manufactured with a razor blade. The pattern was discontinued for a while starting in the late 70's. Since that time, a few have been made.

Pattern # 06

Case has made two different knife patterns that had the 06 pattern number designation.

Case XX Mini Trapper KnifeThe Case Brothers Cutlery Company manufactured a 06 pattern in the 1900s that was a small 2 3/8" Jack knife. This pattern was discontinued at the end of the Case Brothers era circa 1912. The pictured knife is a Case Brothers 7206 pattern with tortoise shell handles.

The second knife to sport the 06 pattern is a 2 3/8" jack knife that is often called a tadpole. They have two blades that open on the right side. The master blade will be either a clip or spear blade, and the second will always be a pen. When the master blade is a clip, the pattern number will be 06 1/2. Case has manufactured them since before 1915 the mid 1960's.


Pattern # 07

The 07 pattern number has been used on two distinct knife patterns.

Case's first 07 pattern was a 3 1/4" whittler that it starting making sometime prior to 1915. They were most often manufactured with a spear master blade along with pen and short clip secondary blades.

Case XX Mini Trapper KnifeThe most recent 07 pattern is a 3 1/2" jack knife that is often called a mini trapper. Most have two blades. The master blade on them is normally a clip blade, and the other will generally be a pen or spay. The spay blade is most common on Cases more recent 07 knives. Most of the older knives (Pre-1980) will have a pen blade. They have been a regular in Cases' production line starting sometime in the 1930s.


Pattern # 007

The 007 pattern was the first Case trapper pattern. It measured 3 7/8" long and was a predecessor to Case's current 54 & 07 pattern trappers. It was last manufactured by W.R. Case & Sons circa 1915. The current 54 pattern was a direct descendant as it was introduced to replace the 007. It is similar in shape & style but larger. the 07 is also very similar in shape & style, but is a bit smaller.


Pattern # 08

08 patterns have been manufactured in at least three different styles. There are two 2-blade versions, and one 3-blade version.

The oldest 08 pattern is a 3 7/8" Jack knife that is known as a coke bottle. They were manufactured by Case sometime prior to 1915.

Case XX Half Whittler KnifeThe most recent two-bladed 08 patterns are pen knives that are usually called half or two bladed whittlers, or swell-center pen knives. The master blade is most always a clip blade, and the other a pen blade. They measures 3 1/4" closed and were introduced sometime prior to 1940.

Case XX Green Bone Split Backspring Whittler KnifeThe three blade 08 pattern is one of a hand full of knives known as a whittler. You may hear it called a split back or split back spring whittler because of the unique spring system used in the knives. It is one of Case's smallest whittler measuring 3 1/4" closed, so you may hear it called a small split-back whittler. This pattern will usually be found with a clip master blade accompanied by a short clip, and a pen blade. Case started making them sometime prior to 1940.

Case XX Cheetah Swing-Guard KnifeThis is a 4 3/8" knife that is most often known as a cheetah or swing-guard lock back. On recent versions, you find that the pattern number is followed by a 1/2L. This signifies that the knife has a clip blade that locks open. This pattern dates back to the Case Brothers era 1896 - 1915. Throughout its existence, it has been manufactured with and without a swing guard and with and without a locking mechanism. Some early patterns have two blades (clip and pen), and no locking mechanism. W.R. Case discontinued it after the 1980 production year, and later reintroduced it in 2002.

They all have a single hawk bill style blade that was originally used for pruning shrubs and fruit trees, but is now handier for cutting sheetrock, carpet, roofing paper and other such materials.

Case began producing these knives sometime prior to 1920, and discontinued them in the mid 1970s. They were manufactured with rough black, bone, and delrin handles. Some older versions have shields, but a lot of them do not.

Pattern # 18

6318 stockman knifeThis pattern is a 3 1/2" serpentine style multi-bladed knife that is one of many that are referred to as premium stock knives or stockman knives. This particular pattern is often referred to as a medium, or junior stockman because of its size in relation to other stockman knives. The blade combination used in this frame has been numerous. The master blade is almost always a clip blade, while the others are usually a sheepfoot and a spey. The pattern has also been produced with a pen and/or punch blade in various combinations. I have also seen this knife with two clip blades extending from opposite ends. Knives of this nature are often known as small or mini muskrats. The 18 pattern is roughly the same size as the 32 pattern stockman, but its bolsters are rounded rather than squared. It looks very similar to the 27, 87, and 47 pattern stockman knives, but is larger than the 27 and 87, but smaller than the 47. These knives were introduced sometime prior to 1940 and to my knowledge have been manufactured every year since.

On recent versions, the master blade will almost always be a clip blade, and the second (when there is one) will usually be a pen blade, a small pair of scissors, or a spey. Some older peanuts have a spear master blade. Peanuts with three or more blades are usually called big nuts. Case began making the pattern sometime before 1915. The handle material used on peanuts manufactured from 1940 to 1980 include black composition, yellow composition, genuine stag, imitation pearl, cracked ice, bone, and delrin. Some older versions have a long pull or have a saber ground master blade. Knives with either of these characteristic are generally more valuable. A few have been built with no left-hand bolster.

The knives do not have a pattern number stamped on the knife, but Case's internal records assigned the 0024 pattern to them. Case began producing them knife in 1958, but they were not especially popular, so they were soon discontinued it in 1961. You could find them sold individually, or with an optional wooden carving block for whittling. The short production span has made the pattern a rare find.

Both versions generally have three blades; a clip master blade along with a sheepfoot blade and a spey blade. Some have five blades; a clip master blade, along with a sheepfoot, a spey, a short clip, and a pen blade. In the past, Case has manufactured a 039 pattern as well. They are 3 7/16" knives that differ ever so slightly in shape, and blade design.

This pattern number was used on a serpentine style jack knife that measures a bit less than 3". Most of them have a clip and pen blade and no left side bolster. They are very similar to the 20 pattern peanut, but are slightly longer.

The 042 pattern has been manufactured as a two bladed knife and as a three bladed knife.

Pattern # 44

As far as I know, the 44 pattern has been manufactured in four variations.

There are two two-bladed versions and two three-blade version.

Case Premium Jack KnifeOne two-blade version is a 3 1/4" jack knife that is generally called a junior premium jack or small jack knife. All of the 44 pattern Jack knives that I have seen have a clip and pen blade that open from the same side. They were introduced by Case sometime before 1940.

Another two-bladed version is a 3 1/4" pen style knife that is sometimes referred to as a half stockman. They generally have a clip master blade and a pen secondary blade that extend from opposite sides. This particular version will normally have a 0 preceding the pattern number. Case started making them sometime before 1940.

Case Stock KnifeCase's most recent three-bladed 44 pattern is a 3 1/4" knife known as a stockman. It is smaller than many of Case's stockman knives, so they are often referred to as small, junior, and sometimes medium stockmans. These knives most always have a clip master blade, and usually a sheepsfoot and pen blade. Case started making this version sometime prior to 1940.
Shop For Stockman Knives

Sometime prior to 1915, W.R. Case and Sons began manufacturing a 3 1/2" stockman with this pattern number as well. They have a clip master blade and a sheepsfoot blade on the right side, and a pen on the left.


Pattern # 45

The two bladed version is a 3 5/8" double end style jack knife that is often called a cigar. They usually have a spear and pen blade that open on opposite sides. Case started manufacturing this pattern sometime before 1915.

Case Cattleman's Stock KnifeThe three blade version is 3 5/8" closed, and usually goes by the name cattleman's knife or cigar. Most of them have a spear or clip master blade along with a spey and punch or spey and sheepfoot blade. The spey blade was used for castrating livestock, which (as far as I know) is how the knife became known as a cattleman's knife. Some versions have a pen in place of the spey or sheepsfoot blade. W.R. Case & Sons began producing them sometime prior to 1915.


Pattern # 0045

Case Scout KnifeThis is a 3 3/4" multi-bladed knife known as a camper's knife, scout's knife or utility knife. You will usually find four blades.

Pattern # 46

This pattern number has been used on at least two different knife patterns.

Case riggers marlin spike knifeThe most recent version is a 4 3/8" knife usually known as either a rigging knife or marlin spike. They have a master sheepfoot blade along with a marlin spike that locks opens on the back side of the knife. These blades are known for being useful when working with rope. The large sheepfoot blade is ideal in making very clean cuts. Rope is easily cut by placing the edge of the blade over the rope and striking the back with a hammer or other object. These knives most always have a bail on the left side as well for easy carry. Case started making them sometime prior to 1940 and they later discontinued them around 1976. Some were produced again in the early 80's.

Case's oldest 46 pattern knife is a 3 5/8" split back-spring hump bottom style whittler. W.R. Case & Sons started manufacturing them sometime prior to 1915. They were made with either a spear or clip master blade on the right side, and a spey and punch or spey and pen blade on the left.

W.R. Case and Sons produced a 3 5/8 " hump bottom stockman knife prior to 1915 that was built on the same frame as the 46 pattern split back-spring whittler. These knives usually have a spear master, and pen blade on front, and a spey blade on the rear.

In 2009, Case brought the 046 pattern number back with a redesigned 3 5/8" humpback stockman, whittler & half whittler knife.

The 47 pattern has been manufactured as a two, three, and four-bladed knife.

Case Double End Jack KnifeThe two-bladed 47 pattern is usually placed in the double end jack knife category and measures 3 7/8" closed. As far as I know, they all have a 0 preceding the pattern number which denotes that the blades will be on opposite sides. The knives normally have a clip master blade and either a pen or spear secondary blade. The spear bladed versions will have a J following the pattern number. W.R. Case began producing them sometime before 1940.

Case Stockman KnifeThe three blade 47 pattern is a 3 7/8" multi-bladed knife that is part of the stockman family. This particular member is larger than most stockmans, so it is often called a large stockman. As far as I know, all 47 pattern knives have a clip master blade, and most often have a sheepfoot and spey blade. Some have been produced with various combinations of second and third blades which includes sheepfoot, spey, pen, and punch blades.Case introduced this pattern sometime prior to 1915.

This number has been used on more than one pattern.

The oldest version of this pattern number is a 3 7/8" lock-back knife that has a single clip blade. This version dates back to sometime prior to1915.

In the mid 60's, the company produced some knives with a narrower clip blade known as a muskrat, or California clip. Knives made with the narrow blade often trade at a higher value. The frame was changed in the early XX era to one that had longer bolsters (less handle material). Some trappers that were manufactured in the early XX era (1940 - 1964) were made on the tested frame which has shorter bolsters. These are much more valuable.
