I love my Blue Spruce marking knife. I love to look at it.
But when I try to scribe with it, it wanders. It is most noticeable when I scribe narrow pins on dovetails. It is hard (even with Brian Holcombe-style Dental chair illumination) to see the bottom of the pin socket through a tail board thicker than 5/8". This means I'm relying on the feel of my knife's registration to the socket wall.
When I remove the tail board, I find sometimes that the knife has wandered - and that's on end-grain. What gives? Any tricks? I've resharpened my knife so I don't think that's the issue; I think it's technique.
Did any of you have this issue while you were learning? And how did you correct it?
