I love multifunctional tools. Sadly, most of them don’t really work very well. Here is one that is a real gem.
The bottom divider is unmodified. Works great, and it can hold a pencil. The top one is modified by having one point ground down. It will not measure quite as small a gap. It is however a much more useful tool. The leather sheath above it holds extra bits and protects the divider.
The bit pocket has a snap at the top to put bits in and a snap at the bottom to pour them out. It is a bit flawed as the sharp bits fall right into your hand, so you need to be careful.
This tool will act as a divider, can draw circles, and cut circles.
First I take a normal bit, and grind it down
The point can be ground by putting the bit in a drill and spin grinding it with sandpaper. It can be done faster on a grindstone or belt sander.
A couple of important points. The flat of the cutter should go to the outside, and should be ground level with one of the six faces of the bit’s shaft. This way it is in line when you cut. The curved edge facing inward, tend to force the cut to maximum allowed diameter, making for a more stable line.
This bit is great for marking wood and leather. As you can see it will also cut. Bits can be made with steeper angles so they do not sink as deep, or with finer points to leave a finer mark. More conventional blades can be made as well.
With a nice divider able to cut, scribe, measure, scratch and mark, you have a pretty amazing tool. With a screw driver handle added to the kit, you can use the blades and points for an even wider range of functions.
I made a better version of the original sheath. Here it is on a belt with a pair of bottle holsters.
The Bit holder uses one snap, and allows you to see and select the bit you want. The bit can be grabbed from the bottom to avoid the sharp points.
I got a bit of feedback desiring one of these made for them. So I have created an Etsy Store to sell stuff to those who don’t feel comfortable making their own. Since one of the major goals of Toolmaking Art is to encourage people to make their own tools, the prices will of course reflect this goal.

check out barbarossaleather.com . We are a boutique tannery in florida and supply all sorts of leathers for projects like these.
I typically delete comments that are purely advertising. It is bad luck to reward spam. However, Barbarossa Leather has some rather cool products, that I could see someone doing good work with and the subject is a good match. So thanks for the link Alex!

[…] I grind the tip off the end of a Harbor Freight Divider. Done! But not entirely. There are a lot more details on my blog, but the real advantage is that you can make your own points. This is an interesting point. […]
This is an excellent idea, thanks for posting it.
