Now that I've got the old knives out of my jointer, does anyone have a good use for used knives? They're pretty good steel so why waste them. I thought about making a set of marking knives. Other ideas?

Made a mini drawknife out of 1 of mine (6" x 1/2"), it worked pretty darned good too!
A successful journey has two parts; facing the right direction, and taking the first step.

It's been a few years back but WOOD did a nice little marking knife project. The plan called for tool steel and I bet a used jointer knive would be just the ticket for that project. You reminded me I have some old jointer blades laying around. I'll have to find them as I just printed that article yesterday.

Well, I have a "wierd" suggestion. I live near the John C. Campbell Folk School in Western NC. Each year they offer a blacksmithing class on tool making. The copy for the class is below.
"Woodworkers and blacksmiths of all levels—forge and heat-treat your own chisels, drawknives, plane irons, gouges, and more. Learn about different steels and how to heat-treat tools in your own shop without expensive equipment. If your main interest is blacksmithing tools, make hot and cold cuts, punches, drifts, hardies, hammers, etc. More advanced smiths can gain an in-depth understanding of various steels."
I know the instructor and I've seen a lot of his tools. He can help you take any piece of reasonable steel and turn it into a fine woodworking (or other) tool. I heartily recommend taking the class. You'll never know what tools you might make.

I can't speak to the OP's reasoning but the last 2 sets I did in my planer and jointer, if I caught new knives on sale I found it was cheaper to buy new ones than sharpen the old ones. I find it hard to justify a sharpening rig for the little I would use it so it's sending them out to be sharpened if I plan to reuse the existing ones. Might get a sharpening rig one day, but for now it's whichever way is the most cost effective.
That's why I have a some old sets of old planer and jointer knives on the shelf right now

I had two reasons for replacing the knives. I don't have the equipment or the skills to sharpen the blades myself so replacement was my only choice. Secondly, the cost of having them sharpened vs. new ones was just about the same. Since these were OEM blades, I thought replacement was in my best interest.
