Do you ever break thin parts, when paring them from a sprue? I did for years. I started out, with the trusted no.11 blade. Shallow cuts that pose some element of danger to the part(and your fingers). Plus, blades get dull. Side nippers pinch the gate and can twist or break the finer bits; and they like to fly away. I now use a knife-mounted saw for this situation. It takes a little longer, but it removes the odd positions to relieve a part of its plastic jail. Just use one blade for parts removal, only. It should last a lifetime. And, no catch bag needed to catch fly away parts.

Drove me nuts! When I got my first dremal that was the main thing I used it for, the small circular saw made cutting small, thin parts from sprues a breeze. Those long thin parts like on a M60 bustle rack were attached in what seemed a dozen places and no matter what you used, knives, nippers, files, toenail clippers, saws, I'd always break it. I'll use my nippers if the part is held at just one point like a grab handle, but 2 or more and I'll get out my new dremal with the flexible extension.

I've broke a few small grab handles, using a nipper. I have a roto tool, but it is .5mm too small to accept Dremel bits. I would invest in one, but I have one in Florida. I suppose that I could have my dad ship it to me.

The first thing I did with mine was to replace the stock quick change collet with a multi pro chuck. It allows me to use any size shank tool without having to disassemble the tool to find the right sized collet every time I swap bit, grinder or cutter. And I have the flexible shaft which allows me to get into tighter spaces. Variable speed, well worth the money.

That's the same setup as mine. I am just wondering how much shipping will be. I'll be moving, into my man cave soon and have the Dremel shipped to me.

For getting delicate parts off the sprue I use a RB Production micro saw. I also use it to remove bigger parts where the sprue gates are large, and snipping may damage the part. If comes in fine and ultra-fine, and with the holder, you can use almost any hobby knife handle.

This is what I use when I need to cut something in very tight spots where none of the tools/saws listed above will ge in close enough.

This is another useful tool:
https://en.wikipedia.org/wiki/Piercing_saw

I just need a hole about 1 mm in diameter (1/25th of an inch or 0.04 inch) to get the blade through and start sawing.
The blades come with different size teeth, both for metal and soft materials like wood and plastic.
It is also great for cutting out large chunks of plastic when opening molded on hatches et.c.

I have used a regular hacksaw for larger, resin pieces. Tt actually worked pretty well.
