The Tail Fin Knife Kit Series is a compact, USA-made fixed blade platform designed for knife makers who want a simple, versatile, and highly customizable EDC or utility knife project. With its streamlined profile, full tang construction, and balanced proportions, the Tail Fin is ideal for everyday carry builds, concealed utility knives, or handcrafted gifts.
Measuring 7.00 inches overall with a 3.25 inch blade length and 0.75 inch blade width, the Tail Fin delivers a compact footprint without sacrificing cutting performance. The hollow-ground blade geometry provides efficient slicing capability while maintaining strength and control in a small-format design that fits comfortably in hand or pocket carry setups.
This is the 1075 high carbon steel configuration, made in the USA and heat treated to 59-61 RC for durability and edge retention. The full tang design includes two precision 0.125 inch handle holes, with stainless steel pinstock included; these holes can be easily modified to accommodate larger pins or threaded fasteners, allowing builders to fully customize their handle construction method. The straightforward design makes this kit an excellent choice for both new and experienced knife makers.
Choose the blade-only kit for full material flexibility, or a combo kit that includes premium hardwood handle scales: Bubinga, Canarywood, Curly Maple, Lacewood, Mahogany, Purpleheart, Walnut, and Yellowheart, each offering a distinct look and finish personality.
Whether used as a lightweight EDC blade, a backup utility knife, or a weekend workshop project, the Tail Fin Knife Kit Series delivers dependable performance and the satisfaction of building a custom USA-made knife from the ground up.
