Have had couple higher quality,widely touted brand name guillotine cutters, that failed badly.
A zeno, cut fine...until screws fell out as it disassembled itself. A Xikar cut nicely, then got a tired,far too quickly, I think, started mangling the cigars.
Have been using a V cutter and a guillotine cutter both are from Craftsman Bench, work very well, don't think calling these heavy duty is right, but the blades in the first mentioned cutters, were very thin, the cutters looked far better than they performed.Craftsman bench cutters seem more solidly constructed without any clunkiness operate in what I'd call a crisper fashion, in that the cutting action is fast, accurate and clean. Don't recall the price, nor where I purchased them.Am pretty sure you'd be able to dredge up some information without too much trouble. They're reasonably priced as I recall. May not be what you want, but might well be worth checking out.
