First off, my apologies to Jon Vojtech, the generous genius behind the UMM product line. Jon graciously provided the Reviewers Corps with a nice selection of new products at the National Convention in Hampton VA, this year, and I am very late in submitting my review.

If you need to make extremely fine cuts in a part – plastic, soft metal, 3D resin, or cast resin material – this tool will do the trick. The blade itself is razor thin (sorry…), coming in at 0.1mm or about 0.004”. Using a blade this thin means applying gentle pressure, letting the very fine teeth do the work – push too hard and you’re likely to bend or snap the blade.

The handle is 3D printed filament, and incorporates a recess for the included Allen wrench that’s used to change blades. And speaking of that, the handle will accommodate a number of blades including the UBT12 Medium Rough Razor Saw.

The quality of UMM products reflects Jon’s background in machining and manufacturing. Perusing the newly expanded UMM website is the modeler’s version of getting the Sears Christmas catalog (yeah, I know, that’s an old guy reference). Highly recommended. Thanks to Jon for the opportunity to review this product and for his unwavering support of all things IPMS.
