Hi Nic, I just wanted to chime in and say how cool it has been to watch you progress. I have very little actual knife making experience but I'm learning and I may have a few suggestions. When drilling the holes for your pins, use a backing block to help with the blow out. Sharp drill bits will help a lot too.
My other suggestion is based on pure conjecture, but I have a feeling that you might be rushing through the process to reach the goal of a finished knife. While I think your style right now is rustic utilitarian, they can look a bit too rustic. If such is the case then my finial suggestion would be to slow down and really take your time enjoying each step. I am a high school girls soccer coach and my team does something similar. They often look to quickly and directly attack the other teams goal, often head on down the center. Yes sometimes it works but usually even then it has more to do with a lucky deflection or a 50/50 challenge that we come out ahead in. What I have been trying to instill, is to enjoy the build up. Pass that ball around the field and draw some of the defenders into bad positions so there will be more space to work for the final couple passes before the shot or cross. Here is where I really see a similarity between playing and knife making, it is during those build up steps that the girls can feel a little nervous and afraid to make a mistake. An errant pass can lead to a give away much like a poor pass on the grinder can leave a deep scratch across the ricasso that you worked really hard to get clean and flat. So they tend to rush through those stages because it is less comfortable, and I have found myself doing the same on a knife that I was working on. What I have to tell myself is not to worry about it, take my time, and enjoy the step at hand. When mistakes happen, accept that it is part of the process and just restart from what ever point is most appropriate. Practice patience and try to enjoy every step. It makes for a more relaxed and better preforming soccer player where mistakes can more easily turn into opportunities. I believe the same holds true for making knives.
Hope this was applicable and not too drawn out. Good luck and I will continue to enjoy watching your progression.
