WR Case Knife Patterns 46-60
Pattern # 46
This pattern number has been used on at least two different knife patterns.
The 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.
Pattern # 046
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 stockman version of the more recent 046 pattern normally has a spear master blade along with sheepfoot & spey secondary blades. The knife has two backsprings. The spear & sheepfoot blades extend fron the front, & the spey extends from the back.

The whittler version of the more recent 046 pattern normally has a spear master blade along with spey & pen secondary blades. The knife has three backsprings. Each blade rides on its own spring with the master extending from the front & the two secondary blades extending from the back. The pattern number is followed with the letters WH on the whittler version.

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

The 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.

I have seen Case use 47 frames to manufacture split-back whittlers as well. All of them that I have seen have a WH in the pattern number.
Pattern # 047
The 047 pattern is the same as the 47 except that it has a muskrat or California master clip blade in place of Case’s normal clip blade. W. R. Case & Sons started manufacturing these sometime prior to 1915.
Pattern # 0047
The 0047 pattern knives are the same as the 47 except that they do not have shields, and they have iron liners and iron bolsters unlike the 47’s nickel silver pins and bolsters.
Pattern # 048
This pattern is a 4 1/8″ serpentine style jack knife that is usually called a bare-head trapper, slim-line trapper, or farmer’s knife. There is a one bladed version, and a two bladed version. The one blade version usually has a long clip blade, and the two blade version normally has a clip master blade and almost always a spey secondary blade. Some were produced with a pen secondary. Neither version usually has a left side bolster. Case has been manufacturing them since sometime prior to 1940.

This pattern is a 4″ jackknife that is referred to as a large or big copperhead. Some collectors call them Vietnam knives. Most have two blades, but some older versions were made with a single blade. The master blade is most often a clip blade, but I have seen some with a wharncliff master blades as well. The other blade is most always a pen. Case started making these sometime before 1915.

Pattern # 050
This is a jackknife that most collectors refer to as a swell center hunter, large coke bottle, or fiddle-back. Most recent versions measure 5 1/8″, but some older versions measure 5 3/8″ and I have seen in a few books that there are a few 5 1/4″ versions listed. The pattern has a single clip blade that is sometimes flat ground and sometimes saber ground. Those with a saber grind will usually have the letters SAB after the pattern number. Some of these knives have been produced with other features including a locking mechanism, and / or swing guard. Case’s 050 pattern dates back to the early Case Brothers era (1896 – 1915), and W.R. Case discontinued them after the 1976 production year. A few were manufactured in the early 80’s. Most have a C preceding the pattern number.

This pattern is a double end jack knife that measures 4 3/8″ (some Case Brothers measure 4″). They go by the names sunfish, elephant toenail, or English rope knife. The master blade is a spear, and the other is a pen blade. Case started manufacturing them sometime before 1915. Many believe that it was first designed to work with rope. The broad blade was ideal for driving through hemp rope with the use of a mallet.

Pattern # 51
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.
Case also assigned this pattern number to their first version of what is known as a hobo. They are 5 1/4″ knives that have clip master blades along with fork secondary blades. The knives split apart to be used together as utensils. Case started making them sometime prior to 1915.
Case’s most recent version of the 51 pattern is a 4″ lock-back knife that was manufactured from the late 70’s to the early 90’s. They have a single blade that will be either a skinner blade or a clip blade that locks open. Because of this they will have an L following the pattern number. When the master blade is a clip, the knife will have a 1/2 following the pattern number as well.
Pattern # 051
This pattern is 3 3/4″ single bladed jack knife that is often called a fishtail. They will have a clip blade and what is called a fishtail left side bolster. Some versions have a guard on. Case started making the pattern sometime prior to 1915.

On the two bladed version you will find that the master blade is most often sheepfoot, and the second a pen. The three blade usually has a sheepfoot master blade along with a spear and coping blade. The pattern was introduced sometime prior to 1940.

Pattern # 54
This pattern is a 4 1/8″ jack knife that is most well known as a trapper. Case started manufacturing them in the Tested era (1920 – 1940). The pattern will almost always have two blades; a clip and a spey of the same length. You may find two variations of clip blades on some older knives. 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.

Another version of the 54 pattern is the hobo. It is the same as a trapper except that it splits apart and has a fork as a second blade. Starting in 2002, Case has manufactured the pattern with a a third blade that is a spoon. Hobo’s have the 54 pattern number, followed by the letters H and B that set it apart.

They have a single clip point blade and measure 4 1/8″. The pattern number is followed by the letter L on these to signify that it is a locking knife.

The 055 pattern number has been used on at least three different knife patterns. There are two versions with three blades, and one with two.

Because of this, it usually has an L after the pattern number. On many of these knives, there are no numbers preceding the 58.
