The KNUTE™ utility knife uses a standard utility blade such as THESE from Amazon or perhaps THESE from McMaster-Carr.
Please operate the lock mechanism as shown below. Do not try to pull the lock bar away from the body laterally.
You can sharpen the utility blade on PFG Stones because the edge is dead straight. It can get rather sharp.
The KNUTE is available only for USA orders, and it is free with your order! Just select the FREE variant when adding it to your order. Heck, you may not even have to ask.
And yes, you pronounce the “K”.
(Note: Just because we designed a knife, and gave it a Norse name, you should NOT confuse us with Grimsmo Knives. Despite the similarities, they are, in fact, different. Go check them out, they make amazing products.)
