Up until a few months ago, I only had the 3" verisons, a PC68, PC10 & BM35. I used to work at Cutlery World in 1986-87, so I got to play with all the different models, everything from Manila Folders, Frost, Rostfrei,and at the time Pacific Cutlery. I always liked the 3" ones the best. They were just the right size for my taste. They were lighter & skinnier and had perfect balance. Then a few months ago, I had the opportunity to get a BM45. Although it had the same narrow handles like my others, it was longer and a lot heavier, but with continuous use I got used to the weight. Now, that the BM42's are out, the Titanium handles have brought the weight/length ratio to a better balance for me. I'm still a little faster with the 3's, but the 42 is catching up. I wouldn't mind seeing a 3" Titanium version.
