Thread: Honing with/without tape... Testing the theories

Carl,

From all the measuring we did in 09 we found that 16 degrees seemed to the mean,,

1mm seems close, the 3M #700 is .0056, we found that on a 6/8 razor 1 layer of tape changes the angle about .60 of a degree

As too off angle razors, yes we found some, but not many, and we also found abnormal heavy hone wear on the older Sheffield razor, dropped the angle, this is one of the reasons I have always thought they have softer spines and therefore are often out of angle...

Steel would make a difference but I doubt that most of the edges on Vintage razors are much different, I also think you are right that they didn't study angle in the beginning they used what worked well and it then the angles were figured later well after it was established... also if the razor you mention at 8 degrees and no hone wear it very well might have been honed free hand with the spine off the hone, or like another thread from 08 was written about maybe a spine guide being used on some of the really old true wedges /near wedges

All this however is just theory still it takes time to prove this stuff out..

My only object with this test, was much like the test I did with the pasted strops with the same razor..

Statements like these, although true are not relevant

Pasted strops round the bevel, or create a concave bevel,, Although true, even after 90 shaves and repeated overstropping with .50 and .25 diamond paste it did not show up..So it is not realative, the edge never failed from it within a resonable amount of shaving...

Using tape will take the razor out of the makers designed angle ... Although true it will happen, it won't happen in at least your lifetime, and maybe not your kids or grandkids so it becomes an irrelevant statement...


I wish more people, would do more testing, it really would help our hobby


edit: Thanks Jerry I just went an measured to be sure
