What's going on in your shop?

I was going to heat treat last night. But, I got into a grinding groove and just rough ground them all. I will heat treat tomorrow. Started with 12 blanks. Screwed up one and ended up with 11.

Dennis, when you full grind like this, do you ever have the problem of forming a "drop/plunge line" at the spine? I have had that problem and was wondering whether anyone else had issues with this too. Thanks
 
Alden - If I understand your question correctly, do I get a bit overaggressive on the grind and leave a plungeline at the spine? Simple answer - Yes. I have done that several times before. Usually when I am trying to do to many things at once or I get in a hurry when grinding. I hate doing this! Although it can be fixed with a quick trip to the surface grinder.

Alright thanks! I'm guessing you could use a disc sander or pretty much anything to restablish a flat.
 
Johan - I noticed this morning that a couple of them have developed a warp. One step forward, two steps backwards. I will try and straighten them in the second temper. Ah crumb buckets ##@@&&!!
 
Well the quarantine has made me focus more on blades than all my other projects.

This is the last knife (7) for a customer's order. The final pic is all of them together, tough to get a group shot and still show details. Clickable thumbnails.

This knife is 1095, brass bolsters, maple burl accents, California Claro Walnut scales and mosaic pins.

Yes. You can hold them vertically (tip pointing down) on your flat platen. Be careful to take an equal amount off both side or your plunge lines will look screwy at the edge. If you take too much off only one side it will make your edge look like it was ground off-centerline.

You will probably have to touch up your bevels to get the grind lines equal at the top again, but it’s definitely a good way to rescue a knife.
