I use all of my knives (around 98), but the vast majority of them don't get used often. The three knives I use often are my Large Classic Sebenza, Strider SMF, and John W. Smith framelock. I use these 3 about 95% of the time with the other 95 knives being used 5% of them time, which means very little use per knife. And of course, within those other 95 knives there are some that I prefer. I have used my BM Activator several times in the past few months while my Buck 110 hasn't been used in months- but I have used it and will use it again.
