Etching folding tool actually, but you'll get the point shortly.
My old Mission Models Etch-Mate is in the bin.
Mission Models appears to be out of business, so a search was done looking for a replacement tool.
Good ole Goggle to the rescue.
I found these guys, thesmallshop.com . They market a number of folding tools and other delightful things for modelers. After some consideration I selected the 4" work station, SMS003 Photo Etch Bending Tool 4" Mk IV RTH Hold & Fold
There was a little delay in shipping, since they were currently making more of these tools when I called, but I now have the tool and I'm very pleased.
I would urge anyone who plans to do any etching folding to consider purchasing this American made tool. This kind of quality is becoming a rare thing these days.
