Dave and others speak of blade thickness in the
FWW article:

snip:
Specifically the thickness of irons. The article listed all of the iron
thicknesses in each review and I never realized there was that much
variation
between makers.  (here talking of the 'factory issue' blades)

I found it interesting to note Garrett's apparent choices in replacement
blades to be Clifton, then Hotley and Hock & LN.  Both the Clifton and
Hotley are noticeably thicker than the Hock and LN.  (0.117" for Clifton,
0.110" Hotley).  Brother Ron says the Hock blade at 0.095" is usable in
most/all older Stanleys and that thicker can cause problems with adjusters
and mouth openings. (if I recall correctly from his web page)  LN must agree
as their Stanley replacement blades are the same thickness as Hocks.

Could it be that Clifton & Hotley are meant for newer (looser) planes and
might have problems in older planes; or that Ron & LN know a little more
about the replacement blade bidness?
