Reality Tormach TV: Knifemaking Tuesdays with Grimsmo Knives

This is too cool.   If you’re into CNC machining, this is great.  If you’re into knife making, this is also great.  If you’re into both – then it probably doesn’t get much better than this 🙂 Introducing Knifemaking Tuesdays John (and Erik) Grimsmo make small-batch production knives and accessories out of their garage in Ontario, Canada, and sell their wares on  By design or by accident, they also make pretty interesting television (full disclosure: Tormach is a sponsor).  Knifemaking Tuesdays is here – an absolutely unique web series on designing, prototyping, machining, and marketing of the Norseman, Grimsmo’s first completely custom knife, as well as his aftermarket accessories for production knives by Spyderco, Emerson, and other manufacturers. Now, on to the Show… Episode Description:  Week 28 – Blades! Waterjet Handles, Blade Fixture This week I got to pick up even more cool stuff from the waterjet place, a ton of titanium handles! They also gave me a tour of the shop and let me shoot a bit of video, unfortunately not of knife stuff but of some other project they’re working on. My brother Erik and I spent Tuesday and Wednesday finish up the huge fixture plate for making blades, and after a few huge goof ups it finally works. Setting it up on the Tormach we tested out the code for cutting one blade, making sure that it’s perfect before we multiply it across the whole fixture and potentially screw up 12 blades. We made 3 test blades, all mostly good but with room for improvement. The new toroid endmill that we’re using to create the edge geometry rocks the house! Leaves a super nice surface finish and removes a lot of material quickly. These blades are RWL34 Swedish stainless steel. Once we go through a few runs of handles then we can take them to heat treat this coming monday.

    Congratulations on sponsoring John, he really is as good as you say!

    I’ve been watching his videos and passing them along for a long time. He’s great and we’ve corresponded quite a lot since he became a G-Wizard customer. I’ve got an anodizing power supply sitting right next to me that’s the same one he uses, LOL.

    Thanks, Bob. I think what John is doing is great and no doubt inspiring to other knifemakers who may not have considered CNC before.
