Nordic Knife Design Korpi 90 Knife Kit With Curly Birch Scales

NKD is the knife brand of Dennis Holmbacka from Finland, mixing old Finnish knife traditions with new advancements in steel and design. The result is a unique combination of quality blades made in proven steels, often mixing traditional blade shapes and grinds with modern tang construction, carry options and weight distribution. 

Knife Making Kit consisting of:

• NKD Korpi Blade blade in stainless steel
• Handle scales in Curly Birch
• Corby bolts for attaching the scales to the blade

How to make the knife:

The handle scales are pre-drilled for the corby bolts. Work required is to flatten the back of the scales on sand paper until really flat, then epoxy them onto the blade and adding the corby bolts. When the glue is dry, file the corby bolts heads down until flush with the handle scales. Shape the handle with belt sander, files or similar until you are comfortable with the shape. Then sand with sand paper to a high grit (1200?) and seal with Uncle Bjorn's Handle Finish, Tung oil, wax or similar.

Note: This kit does not include a sheath.

This fulltang knife blade has the profile of the original Tommi puukko, with handle scales in Curly Birch and with brass corby bolts. The knife comes with a leather sheath in traditional Nordic style.
The Tommi knife is one the most well know Finnish puukko models, developed in the area of Kainuu in the east of Finland around 1860.
