Which Frost?
Jim, Family, or the Puukkos?
Frost (Family) "Made in Pakistan" knife shaped objects are far below the old "Made in Japan" (or Taiwan) no name "gas station special" knives that sold for a dollar or less at DX, Phillip 66, and Union 76 service stations back in the 1950's and 1960's as far as quality goes.
Truthfully, "Frost Family" knife shaped objects have never been noted for so much as "mediocre" quality.
If you have enough of them in a bag, they MIGHT make a good kayak, canoe, or surf board anchor.
From what I've heard, the Jim Frost, and the Frost Puukkos are of good quality. I've never owned or handled one, however.
They cost considerably more than I am able or willing to spend.
I avoid everything with "Frost" in the manufacturer's name, and strongly advise others to do the same.
If you have to get a knife at the Frost price point for whatever reason, get a recent offshore made Imperial, instead. They are a much higher quality knife across the board than a Frost Family knife.
If you want a good inexpensive high quality traditional folding knife, try Rough Rider, Marbles, and BTI contracted Old Timer and Uncle Henry.
(the BTI contracted Imperial's aren't bad, but the Old Timer and Uncle Henry are better.)
Marbles recently came out with a series with D2 blades and black canvas Micarta covers for under $18 retail. I have one of the MR431 Sowbelly stockmans from that series. I am very happy with it, and "EDC" it. (I don't change my knives on a daily basis.)
DISCLAIMER:
I "don't do" modern one hand opening or flippers, liner/frame locks, thumb studs or hole, or pocket clips, so I cannot comment on the quality of their offerings in the "Modern" category .
I've never tried one of their fixed blades, either, so I don't know about the quality of the Rough Rider, Marbles, or the various Schrade brands fixed blades.
Therefore I have no comments as to quality concerning their products outside the traditional folding knife category.
