I have a few customs, and I use/carry them in rotation daily.
But I just got back my Larry Chew Covert D/A today after 9 months that I shipped to him to repair for a broken spring. He has had some personal problems, and I don't blame him, but if I had kept it in the safe it would still be working. On the other hand it probably would have broken anyway down the road sometime he said because it was a faulty spring. He refurbished it, repaired it, and now it looks just like new, and I don't know if I want to use/carry it, and mark it up again being it was a $725 knife.
I do have several other custom folders, and some of those are D/A also I do carry, it is just the Larry Chew is my favorite, and hard to store it in the safe when I want to carry it, and enjoy it for it's quality of workmanship, the 440V steel in the blade, and the awesome toy factor in such a quality knife.
I just got it back today so I think I will just look at it for a few days, and decide whether it is worth taking the chance of it breaking again.
I do buy them to use, and enjoy though, and usually it does not take that long to get a repaired knife back from a knifemaker, usually 2-3 weeks.
I hate decisions
