I just recommended Wiha torx bits on the knife modification and repair area a day or so ago. In fact I was looking on Amazon yesterday and noted that one of their vendors, Micro-Tools, had an incredible buy on Wiha torx bits going on. Packages of 10 bits for under $1.35 per package. The total bill, including shipping, for ten each T6, T8 and T10 bits was $6.30 which I consider an incredible bargain. Should be enough bits in those sizes to last a long time.
