anyone used the Dremel XPR multisaw for cutting soft metals ?

I've used mine [part of a "kit"] for cutting wood, plastics, and metals (both ferrous and non-ferrous) - with appropriate blades, of course - and it does an reasonable job of imitating a jig/scroll saw.

It has one attribute that's come in handy: it can be used in very tight quarters!

OTOH, if you have the space to work, nearly any toothed-blade saw can be made to work with varying limits of accuracy: a fixed carriage saw [chop, Radial Arm, Miter, Table, or Band saw] will provide a more accurate cut angle/placement than will a hand-held saw. A plywood/veneer blade, mounted so as to rotate backwards, works nicely in a circular saw and doesn't dull the blade.

If you already have one, and no other, use it.

If you have any other kind of saw, you can use that.

It all depends upon what you already have on hand OR can, otherwise, justify for future projects.
