Hey Rob,
Think about this for a moment. Your (well my) drill bits are titanium plated. I am not great at sharpening them, so they sometimes get VERY hot, but the titanium is still on each of the 114 pieces that I bought for $40. So for an average of 35 CENTS they could make drill bits that average 3/8"--larger than MOST kits.
So, the plating cost is established as under a buck. NOW, the pen kit manufacturers know you want to HEAR you are getting Titanium. They also know you have no means to test their assertion.
Do you suppose some may LIE?????
I believe this is more likely than the premise that you HAD titanium and someone gave it more wear than my drill bit (especially the 25/64 which has drilled easily a thousand cigar pen blanks).
Don't damn the plating, damn the plater!!
