Hi, I just bought a Gerber Coburn Triumph edger and would like to know if anyone can tell me if only certain blockers are compatible with the chuck that this edger uses? For example, there is a Nidek Ce-1 blocker that I'm interested in buying, but haven't bought it yet because I'm afraid that the blocks for it will only work with a santinelli edger. Can anyone give me some input if all blockers are universal and would work with any edger brand?
