Finding a good source for Torx screwdrivers useful for our Kershaw knives turned out to be harder than I expected. Sears had some listed, but there were out of stock and rather expensive. Lowes has a screwdriver set with bits, but the grip came apart immediately and the bits don't have sizes on them. Finally, I a set at Home Depot for $6 that's solidly made and works well.
Hopefully, this will save someone else the search for these.
