The Sifu may have my favorite blade design of all time. The blade geometry excels at push cuts, pull cuts, and tip work. It cuts cakes as well as it cuts wood and rope. The knife also has a grip that makes it impossible to slip and is comfortable in multiple positions.
My one complaint is that I found the knife awkward to open. The clip's position means that you pull it out of your pocket by the tail, then have to shift your hand all the way forward on that long grip to operate the thumb stud. My fix for this was to add a kydex "wave" attachment that is held in place by the thumb studs. Drawing the knife from your pocket catches the wave and opens the blade.
The other modification I made was to swap the blades between my two Sifus. I prefer the green scales, but the D-2 blade is an improvement over the ATS-34 version. This way I get the best of both.
