Another shop-made tool: marking/striking knives (6 3/4" long)

This idea is from the Popular Woodworking’s 149 Best Tricks of the Trade, turning spade bits into marking knives (p. 27).

I used a Dremel to shape the tools and a grinder to create the bevels, followed by the MKII power system to flatten the backs (a water stone can be used instead). Autosol is what I usually use to remove rust from my hand tools. The magazine doesn’t specify the angle for the V-shaped tip; I chose the one found in the Veritas striking knife (50D01.01). The walnut handles were turned on the lathe, with mineral oil and wax as the finish.

The last picture shows the lines cut with the shop-made marking knives.

I like the idea of using the bit after it is worn out. I have a couple of candidates in my bit drawer.

Nice work on those. How did you do the initial cuts?

TS: initial cuts – if you mean cutting out the V-shaped tips, I used a Dremel fitted with an abrasive wheel like this http://www.best-price.com/product/dremel-420-20pc-heavy-duty-cut-off-wheels-xjb74/97106279/1/

You can use a grinder or even a hacksaw, if you don`t have a rotary tool.

Thanks to all for looking.

Guess I missed the point, (pun initended) ;-)) I would have thought they were harder than that.

You can always anneal the bits and re-harden them after they are shaped. Granted, this takes a torch, but who doesn’t love playing with fire! :)

Nice tools. And usefull too. Great job. I like the idea of using the Dremel to make the cuts. This latter should be used more often my shop! I think I will get mine out of the box!

Thanks. I will remove the one I have in my wish list at LV (LOL).

Question: How many disks did you used to make the four cuts? They are so britle!

Good idea to use old spade bits! I have made some from worn out HSS jointer knifes and also works very well.
