UMM-USA is dedicated to fine scale modeling, encompassing model kits, accessories, and specialized tools.Owned by John Vojtech, a fine scale modeling veteran. UMM-USA is an on-line Store, importing and exporting kits, modeling tools and supplies, and seeks and offers solutions on technical issues. In addition, his services currently include design and production of master parts, casting of original masters, photo-etched masks, decals, and building made-to-order models for customers. You can see a sampling of John Vojtech's finished projects in the Our Gallery section of the Web site.

John Vojtech was born near Prague, in the Czech Republic and currently lives in Deerfield near Chicago, Illinois USA with his family. As a young boy, John was taught about the modeling by his father. This passion for modeling led him to later teach modeling theory and practice at the elementary, middle, and high school levels. What has long been a hobby is now his profession. Drawing upon his success, John has expanded into new fields, offering consulting services, teaching, seminars, exhibitions, as well as continuing to teach modeling theory and practice to the young generation interested in this work. John Vojtech is also a member of IPMS / USA International Plastic Modelers' Society (National), member of IPMS / Richard I. Bong Chapter (Milwaukee, Wisconsin), IPMS / Lakes Region Scale Modelers (Crystal Lake, Illinois), IPMS / Butch O'Hare Chapter (Downers Grove, Illinois) as well as AMPS Armour Modeling Preservation Society (Illinois).

The UMM13 Ultra Micro Chisel features a 2.5mm wide flat double-beveled hardened tool steel blade. The ergonomic knurled plastic handle provides a good grip to easily control the blade. A good addition that John has added recently is the plastic guard to protect the blade.I’ve used this chisel on standard injected plastic parts, cast resin, and 3D printed resin. I have used it both as a cutting blade and as a scraping edge with great results either way. The edge is quite sharp and takes little effort to remove mold lines. As a chisel, it can easily remove pin marks, especially in tight, deepy recessed areas.I can easily see it being of value in removing molded on cockpit detail in preparation for 3D decals from Eduard or Quinta. This chisel can also be used as a cutting tool to create grooved lines or louvres in plastic parts.

You won’t need to press hard for it to cut, which is a good thing. When using chisels, its always better to not hurry. Proceed with a light touch, then follow up with increased pressure on additional passes until you are satisfied. It is easier to make an additional pass then to dig too deep and make a mess.

Having the proper tools for your project will help you to achieve a higher level of quality for your “build”. UMM-USA scribing tools fill that role. For those of you who attend IPMS Nationals, you should find this at UMM-USA’s table and John Votech will be happy to give you a demonstration. You can also find it on his website above. This product is a superb tool based on the high quality of the cutting point, comfort, ergonomics, and ease of use.

Highly recommended!

My thanks to John Vojtech and UMM-USA along with IPMS/USA for the chance to review this great modeling tool.
