/diy/ - Do It Yourself

It's a more comfortable handle for pic related, a rotary cutter for fabric. If you cut a lot and don't want to shell out money for a proper industrial electric rotary cutter, these get very uncomfortable as you have to bend your wrist to apply more pressure.
The blade will of course get a guard, and the part where the hand itself sits will get a more comfortable wooden handle -- the metal part is basically the "tang".
I omitted these details because they seemed irrelevant to the question.
But looking at your picture, using just a bit more material that covers the upper part of the blade is an even easier way to attach a guard. Thanks!

Some hard plastic would definitely be an option. As I will be using commercially available replacement blades with the OEM "shaft", washers, etc, I have a maximum thickness of 6,5 mm at the blade. It seems to me that I'd have a lot more work shaping a thicker plastic to the right dimensions than just working with the steel. I also have no idea what kind of plastic to buy.
You think I will have a lot of trouble cutting out that shape with an angle grinder and drilling a few holes? I mean I don't expect to be finished in a minute, but surely an hour will be enough to work through ~30 cm of ~3-4 mm steel.
