I recently had a Geneva rescaled and had to re-hone it. It had a balsa edge and shaved extremely well. Last night I took it to 14k and shaved with it this morning. While the 14k was smooth and effective it didn’t come close to the diamond edge in comfort or effectiveness. I’ll fix that today. I’m playing with 14k with a couple of razors now but the Geneva won’t be one of them. I think the pasted balsa edge is simply unbeatable - even by the jnat edges I’ve used. Most likely ease and low cost diminishes its popularity.
