All About Pocket Knives

Got a dagger last week... Boy is this one is a beauty.. super clean lines, the blade is superbly made in Japan... Very nice grind lines and perfect bevels...
Nice red bone handle, seems like original sheath came with it...
But I have no clue where it comes from and who made it in Japan for Frost... Phil Mann design on tang!!
Like to know what year it was made and more info about the maker!!
Considering a trade for older pocket knife!
Tnx!!

If that knife is stamped with the Frost Cutlery logo then it was likely pirated from Stewart Taylor who released that knife many years ago under the Taylor Cutlery brand with credit to the design by Phil Mann on the pile side.I have one so marked.
