A New John Grimsmo Knifemaking Video with some G-Wizard Tool Deflection Work

If you’ve been reading our blog for very long, you’ll know we’re fans of John Grimsmo’s knifemaking videos. In them he uses a little hobby mill to make custom parts for knives, which he sells to collectors. There is a lot of fascinating and useful information in them, but beyond that, they’re just fun to watch if you have a few minutes and any interest at all in knifemaking. Here is John’s latest video which covers a variety of topics:

In this video he’s working with some Swedish stainless that is well thought of for making knife blades called “RWL34″. The blade design itself is interesting, and John works through a couple of problems he encountered working this tough material, including breaking an endmill due to excessive deflection. He uses G-Wizard to figure out how to reduce his depth of cut to keep deflection within allowable limits and shows all of this in the video. It’s a pretty long video (over half an hour), but he has a lot of detail to show folks about how he approaches his work.

Given how expensive good cutters can be, a tool like G-Wizard can pay for itself pretty quickly if it helps you avoid breaking your cutters. If you’ve never checked out our G-Wizard Machinist’s Calculator, sign up for our 30-day trial, it’s free!
