I say I like a half guard on the basis of a safety issue. It depends on various items weather conditions used in, purposes of useage, it's not always necessary I can agree. I know a guy always stabs his knife in a tree or branch when not in use instead of his sheath, his fingers have gone down the blade more than once and he still does it. He's a logger, he's more worried about a tree falling on him, than his knife killing him.
A knife use to be a sharp cutting tool in the past, now the standard is these knives are like razor blades or scapels. In the past you could cut yourself and it was just a cut not to bad, you make a mishap with a knife nowadays you could be going to the hospital for repairs.
You did a great job and I went with your recommendation and agree a guard would have looked odd on the Wharncliff, all is good. Looking forward to seeing the other wharncliff blades you make.
