Krzysztof Dabrowski from Poland has a lifelong interest in the subject of military aviation, and has written dozens of articles on a variety of related subjects for printed magazines and the ACIG.org/ACIG.info, AeroHisto and The Boresight websites. His particular area of interest is the air warfare during the Cold War, the aircraft involved, and the experiences of their crews. This is his first instalment for Helion and he is working on a second title (Dropping the Big Ones: Live Testing of Soviet Nuclear Bombs, 1949-1962) for release in 2021.

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.
