Vintage Case XX “Shark Tooth” Lockback Knife w/ Sheath – Model P187L00P – USA

A bold and unmistakable design from Case, this Shark Tooth lockback stands out with its sweeping profile and robust build. Featuring a single locking blade and contoured handle, this knife was built for real use while maintaining the collectible appeal Case is known for.

The dark wood handle scales paired with brass bolsters give it a classic outdoorsman aesthetic, while the included original leather sheath completes the package. This is a knife that bridges the gap between functional carry and display-worthy craftsmanship.

Condition

This knife is in very clean condition with minimal signs of use. The blade retains a strong edge and opens smoothly with solid lock engagement.

There is very slight side-to-side blade movement when open, which is not uncommon in some lockback designs and does not affect functionality. No significant wear or damage noted to the handles or bolsters. The sheath is in good usable condition with light age and handling wear.

Historical Note

Case introduced the Shark Tooth series as part of a push toward more modern, rugged lockback designs while still maintaining traditional materials and American manufacturing. These knives gained popularity among outdoorsmen for their durability and distinctive shape, making them a recognizable departure from classic slipjoint patterns.

Collector’s Note

The Shark Tooth occupies an interesting space in Case history—less traditional than their classic folders, but increasingly appreciated for that exact reason. Complete examples with original sheath, like this one, tend to draw attention from both users and collectors alike.
