Pattern # 16

There are at least two knives that were manufactured with this pattern number.

One version is a 3 3/8 " jack knife that Case started producing sometime prior to 1915. Most of them have a clip, or spear master blade, along with a pen secondary. Most have no left side bolster, no shield, and almost all have bone handles. Case discontinued the knife in the late 1960's. 

Another version was introduced in the early 1960's.  This one is a 3 1/2" knife known as a budding or grafting knife. They have a single spey blade, have no left side bolsters, and I believe were only made with wood handles.  Case discontinued this knife sometime in the early 70's.

Pattern # 17

This knife is a 4" jack knife that is generally referred to as a half hawk bill or loom fixer.  They will normally have two blades that extend from the right side.  Most of them have a large sheepfoot master blade and a pen secondary blade.  Case introduced the knives sometime before 1940. The handle materials used on this pattern include black composite, bone, and laminated wood. The black composite handled versions can be found from the pre 1950 era. All were made with laminated wood after 1970.

Pattern # 18

This 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.

Pattern # 20

This is a 2 3/4" serpentine style jack knife that almost all collectors call a peanut.  They usually have two blades, but some have been manufactured with one, and sometimes three or more.  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. Some of these have a 0 before the 20.

Pattern # 21

The oldest version of the 21 pattern is a 3 1/4 " whittler knife that W.R. Case & Sons started producing sometime prior to 1915. All of them that I have seen have a spear master blade, along with a pen blade and a short clip blade. I believe some have wharncliff master blades as well.

Some have a spey master blade and a sheepfoot secondary. Some have a sheepfoot master, and a pen secondary. Others have a razor master and pen secondary. I believe they all have black composite handles and no shield. Case produced this knife from sometime prior to1940 into the late 40's.

They came with a wooden carving block.

Pattern # 26

This pattern was only manufactured by Case prior to 1940.  It is a 3 " serpentine style jack knife that has two blades that both extend from the front.  The master blade will usually if not always be a clip and the second a pen blade.

Pattern # 27

Case manufactured at least three versions of the 27 pattern. Two have two blades and one has three.

The oldest version of the 27 pattern was a 3" congress style pen knife. They were only manufactured with two blades as far as I know.

The most recent two bladed version is a jack knife that measures 2 3/4" closed.  Most collectors call them baby or small premium jack knives.  I believe the master blade will always be a clip, and the second  a pen blade that both open from the same end, and each ride on its own back spring.  They were introduced by case sometime prior to 1940. .

The three bladed version is one of many knives known as a stock knife or stockman.  It is among the smallest stockman knives, measuring only 2 3/4".  Because of this, it is often referred to as a baby premium stock knife, or small stockman.  This knife most often has a clip master blade, along with a pen blade and sheepfoot blade.  Case started making them sometime between 1940-1964.
