I've owned several "grails" and I seldom keep them. The most recent grail to leave my hands is this early Walter Brend #2. I carried it maybe a total of 2 weeks and realized it's too amazing to use.
I've been collecting knives for a long time and I sometimes think we deserve to actually use some of the amazing knives that we have. I understand how we don't seem to hang onto knives for very long, for various reasons, but I'm getting to the point where I want to pick a few that I am actually going to keep and use, or at least use as if I intend to keep them. I get tired of babying and not using knives because I don't want to damage them and I might want to sell them. I'm picking at least a few of my knives to actually use.
