Thank you very much for this review. It's nice to hear what can be improved, and what I did right as well, of course.
I believe both purple handles from last batch were Box Elder burl with nickel silver pins. The spine was rounded a bit, but the choil was not. I made a decision to keep the spine a little more square than most knives that I round to give it a little more surface area. The more you round a spine the thinner it gets at the top, making some thin knives uncomfortable when pressing on such a thin spine. I think that I'll round the next ones even more, as well as the choils which was already planned.
About the edge: The initial bevel was ground with a 120 belt on my 2 x72, then finished with Shapton Glass 320, 500, 2000. Admittedly I didn't do much in the way of deburring the edges because I thought it didn't need it, but your comment about losing the initial edge fast means that there must have been some burr left. 52100 is not a high alloy steel, but it shouldn't lose its edge fast like you stated. I shall step up the sharpening game on next batch. I'll probably take them to 4k as well instead of 2k.
I truly am grateful for your comments as this is the only way I'll know how to improve my knives. There are quite a few custom makers on the market right now, but I feel I have a duty to CKTG and this forum to make something special for a good price. Maybe one day I'll charge more for my knives, but the thought of making something affordable feels better in my heart. And rest assured, any criticism or comments are taken seriously, and I thank you for them.
