I just replaced the knifes in my (new to me) delta 15” planner. The old ones are overdue for sharpening or replacement but they are still nice looking knifes. I can’t see me throwing them away, but I don’t want them to nag me to make something of them or put them to use every time I come across them in the bottom of a drawer either. I never made a knife, but I guess one of these blades could be shaped into a pretty impressive dagger with a Rosewood handle and a nice brass guard. Not sure what I would use to shape and sharpen the blade, but I’m pretty sure I have something that would work. Have any of you made something useful or gorgeous from your old blades? Any tips on working with the steel?

If they are still in good condition why don’t you have them resharpened as a spare set. Sods law states that while the others are are the grinding shop you will need a set of blades on the hurry.

i wouldn’t use them for a dagger, they will be too brittle for that I would have thought.

I was given a number of sawmill planer blades, ground down to much for the mill, and some that didn’t meet therir standards.
I swaped some to the blacksmith at oiur local historical site for a hand forged gouge, another became a hook knife, the rest are in that drawer, but the converts work very well.

Use them for tearing sandpaper.

Keep them in the drawer for inflicting severe wounds on unsuspecting fingers. DON’T ASK!!

Could you add a wooden handle and make some type of scraper? Could be good for scraping glue or whatever.

I’ve had my 12.5” Delta ones with nicks re-ground as a spare set.

You could always cut one into a few pieces and make some nice scratch stock blades.

I don’t do machine work but had a machinist put a handle on either end and I use the blade for scraping hides while tanning. Completely different website, but they work great for that purpose.

I could see doing the same thing and using it as a scraper for wood. It would be a great draw knife.

I’ve yet to have any unusable planner/jointer blades in my collection, but if I did. I could see using them for small hand plane blades, making molding cutter blades, small hand carving tools, or for making marking knives and the like.

I’d have them resharpened and keep them on hand. That said, I did give some jointer knives away (changed the cutterhead) and at least one guy said he wanted to make a marking knife out of one of them.

Thank you for the responses. The most logical use (to me) is to have them resharpened for the next change out. Why I didn’t I think of that????

it depends on the planer. Some of the lunch box planers with dual sided blades don’t do well with resharpened blades.

I stack them on the cart below the planer. That’s as far as I got.
Rough planing barn wood?
Resharpen with a honing guide?
