Precision Sprue Cutter
Precision Sprue Cutter/Small Sparts Remover

A month or two ago after attending a model show in Seattle I happened to find myself looking into a new razor saw based upon the recommendation of another modeller. The one that he suggested was from a company called UMM, or Unique Model Master. While I came for the saw I found myself looking at some of their other tools as well. One that caught my attention was a small parts sprue cutter or Precision Sprue Cutter.

Too often I have found myself staring at the broken end of an MG barrel only because it snapped off removing it from the sprue. Even if I take extra care with my Xuron cutters, I have found that things will break as the sprue can twist under pressure, leaving me with a part that needs replacing. Not fun.

So when I noticed this little tool I thought for under $10 it seems worth it. I am already paying for the shipping, so why not? The saw I knew was going to be good, but when they arrived I found myself wanting to try the small parts cutter out. During the construction of my recent Leo 2A3/4 build I used this little cutter as much as I could. The results were even better than I hoped. For the price I got a small parts remover that is sturdy and precise. No small feat.

What is great about this tool is the way it is designed. I found that there was no place on the tree that it could not fit with some minor twist or turn. The cutting edge is nice and sharp and makes quick work of those fine sprue attachments and it fits right up against the part so you get a nice flush cut 95% of the time. I found that only every once in a while would there be a small burr that needed to be removed with a sanding sheet or hobby knife. Best part is it works really, really well on those small fiddly little fragile parts and there has been no breakage on this project as a result, woohoo!

The only down side is that it does not work on larger parts with thicker attachment points, but then again, its not meant to. I have no idea if this is old news to all of you or if this is really a great find that other have yet to discover. Either way I am sold and I may order another one or two for my kids. They are that great, the tools not my kids. UMM has many other tools available on their site including that awesome razor saw and many different tweezers and scalpels. They also have some great punch and die sets as well.

Outstanding design and construction. Works flawlessly. Cheers.

UMM Unique Model Master
Highs: The UMM Precision Parts Cutter is one of the BEST tools I have purchased in a long time. Not only does it do what it claims but it does it with precision and some great atheistic. It really is the best tool I have found.
Lows: It is not meant for larger attachment points so donít use it as an all purpose cutter. This is a fine instrument just like that .2mm needle on your brush. Treat it with care and use it on the intended jobs only.
Verdict: For under $10 it is a great tool to add to your bench and no serious modeller or hobbyist should be without it.

About Damon (didgeboy)

I have been "building" models, collecting and starting mostly, since I was a kid and really started getting into it in my teens. The Tamiya kits if the 80's were what did it for me. I actually became a tanker in the US Army just to get a chance to study the Abrams up close (and drink German beer). I...

I actually have a pair of these as well which UMM gave to me in Orlando. I have used them and they do work very well.

I purchased a very similar item from Micro-Mark a while ago, and have used nothing else since. It's a great little tool. Cheers, Mike

I too bought something similar from Micro Mark and it sure it's useful to cut those really small and fragile parts from the sprues. Rob

The micro mark is the same thing but more expensive, believe it or not. UMM also makes a killer micro razor saw that should not be missed if you do any scratch building or conversions.
