Looking at a few used shaper cutterheads, and I’ve never heard of these brands before. Gladu, misenheimer, and EK Wood. Gladu, might be a Canadian company that looks like they make spiral moulder heads, but these are all insert heads. Can’t find anything in ek wood, and misenheimer might be a custom outfit out of TN, misenheimer saw company. Any of you folks know of these brands? Good, bad, ok? They are insert heads, so I don’t particular care if they are still in business or not, because I can have kniv3s made at a few places. Oddly enough, I think a few of them might be 40mm and 45mm.
