I though chemical sharping was an acid dip, It used to be common to
"sharpen" files by dipping them in sulphuric acid. Now it's cheaper to
buy a new file and throw away the old one.

I mistated my question above.
Apparently "chemically sharpening" is a plating process, perhaps similar
to
electoplating. I cannot find out much about it on the internet. All
hooks
are rasonable sharp when originally ground, but "chemically sharpening"
defines the edges better, and makes it sharper. This extra sharpening is
rapidly lost in salt water, perhaps as the salt dissolves the plating.
Neither the Teimco nor the Mustad stainless steels hooks are "chemically
sharpened". Both are unplated stainless steel. Tiemco on their web page
states that the process of making stainless hooks precludes chemical
sharpening.

My question was "what evidence do you have to state tht Tiemco stainless
steel hooks are sharpened differntly than the 34007?

What do you mean by dull?

Are you sure that the Japanese hooks(Tiemco) er that better than
Mustad
for
example?


I believe that chemically sharpened hooks are sharper than mechanically
sharpened ones. Although Mustad's more expensive hooks are chemically
sharpened, the Mustad 34007 is mechanically sharpened.
