What is it that you want to know? If you are askng for the definition of a plunge cut, it's the area at the rear of the blade just in front of the ricasso where the edge starts (the part of the edge furthest from the tip). It's that deep plunge where the grind starts.

If you are asking for tips on how to do it, the fastest way to get that info is by using the Search button. There have been many discussions on making the plunge cut. Check out the Sticky note at the top of this forum for a tutorial. I think Terry Hearn 's tutorial covered the plunge cut, it's called something like "Let's Make a Lil' Skinner".....

I have been forging for about 6 months and my fist 20 or so blades ended up in the trash, mostly because of unfixable screw ups doing plunge cuts. Then one day, I had what my late grandfather used to call a "rush of brains to the head." I took my filing jig that I bought from Uncle Al and just put the blade in backwards and stuck the blade on the platen using the jig as a stop. Voila!!!!!! As perfect a plunge grind as a ham fisted newbie like me is likely to get. I use 100 grit Norzon belts for this and then clean up freehand with 220 and 400 AO belts. Much higher success rate.

I was thinking about that.... using a filing jig on the grinder to get straight plunge cuts.


anyone think that's a bad idea?

I made a simple jig out of two pieces of hardened but untempered O1 (very hard steel). There is a screw through both ends of the steel and the blade slips betwee the two pieces, tighten the screws. I usually do not feel the need for this assisstance on a regular blade but with daggers I often use it since they have twice as many plunge cuts...
