Multi-Tool Did I do this right?

I am working on a sort of generic Multi-Tool, and I ran into a roadblock.

The cutters that sit at the base of the jaw have one angled face and one flat face. So you either end up with a bad edgeloop, a couple of Tri’s, or trying to get rid of an extra edgeloop. Its kind of the same problem that you face when modeling something that has threads on it like a screw. At the top and bottom you end up with at least one tri.

In order to get rid of the Tris in this case I connected the two opposed tri’s accross the angled face of the cutter blade. Was this the best way to do this? Im sorry if this doesn’t make any sense, I actually had a really hard time verbalizing this. You can see what I am talking about in the attached image.

and here is the Blend

Thanks in advance.

I’m not sure if this is what you were wanting, but I fixed the triangle problem, deleted the other half of the cutter. MultiTool.blend (305 KB)
