Homebrew PCBs

Well, if I cut a very narrow 1/8" sliver off, yea it curls a lot... even a 1/4" slice will curl some, but for normal cuts, both sides stay flat.

As to how long it will hold up?  I wouldn't think in a factory production where it makes hundreds of cuts/day it would last long, but for home use where 5 or 10 cuts/week are done, I expect it to last a good while.... years? The blade can always be sharpened if need be.  The $25 should hold up longer.  I think that is the one I would get now.

For the cost and ease of cutting - these are my choice, and if the PCB is the .032" to .040" it just "slices thru" really good.  Only the heavier .062" do I have to really hold tight when cutting.
