Modifying Blade Shapes on Modern Designs

View attachment 837902 The tips on all these knives were reground on a 1X42” Rockwell belt sander with a contact wheel using successively finer belts and a big bucket of water.

Here is a CRKT jettison I modified (removed the "fin" on the spine) using my 1x30 and a few belts, finished with a 1200 ceramic belt.

What it originally looks like

After modifying

​

This took all of about 10 minutes on the sander with 3 belt changes.

I also did the spine on this Bad Blood Dreadnaught the same way and reduced the size of the flipper tab.

Some cool mods, it always helps to have before and after pics.

Nice jobs but how about the heat treating of the blades, aren't you concerned with that? I understand that you don't want the steel to get hot but..................

Easy question. I dip the blades in water after every pass. They never get too hot to touch. The Stellite blade on the Boye knife is not sensitive to overheating, but I dip it anyway. Can’t teach old horses new tricks.

Meh, I'm not a knifemaker but...

Annealing begins at 260C or so, so if you can grind it and touch it without hurting yourself, no biggy.

I've also reground the spine to reshape several modern folders. I use a small bench grinder, lots of water cooling and then diamond files and fine, finer emory to polish the spine. No big problems.
