He's got a carto punch in his mod Squad section now. Looks like I don't have to order something expensive across the border and can avoid the hassle of using my saddle valve punch method. I wonder if the location of the screw is at the right height to punch a carto while it is on my mod. It looks like it.
Nice. For $2 I've gotta try that with my next order, better than a $10 saddle valve or the $15 Siam mods punch. I wish it had a wingnut though, it's hard to tell much from that picture.
