Snap-on no guarantee? (NAC)

[tihol_tiholov at sd27.bc.ca]

This is a question and a mild rant:
A local Snap-on rep told me yesterday that there is no life-time guarantee
on torque wrenches, particularly the part that sets and maintains specific
torque.  If used as a 2 way breaker bar - oh, yeah, that's guaranteed.
Now, that maybe so but it's funny nowadays since Canadian Tire gives
life-time guarantee on their torque wrenches (I asked specifically
yesterday) in full.  I also have a Husky piece, for which I was promissed
life-time guarantee - haven't tried it yet, it still works.  I haven't
heard from Snap-on yet, that's why I'd like to ask if anyone knows or has
used such guarantee from Snap-on or Husky.

TIA

BTW, he wanted $125 CDN for repair and I left him the wrench, since I
didn't ask in advance about costs thinking it was covered for life.  A new
Canadian Tire one costs $92.
