On this forum a lot of people look down there nose at any thing other than high price tag name brand knives. Man, You mention Frost or Rough Rider S&W and you could get BB as some kind of whack job knife terrorist.
Frost Cutlery is a company based out of Tennesse i think, that imports knives from China and Pakistan, stamps their name on them, and sells them. There are different levels of Frost Cutlery knives. 95% (at least) are junk. There's no getting around that. I have a box full of folders that were given to me, or that I won in auction lots, that I would not use to open an envelope. The ones that will lock, can be closed by hand without unlocking. That said, they occasionally do stick their name on something decent, like the Steel Warrior series, which get lots of praise on this site. I have one of their Apache something series that is very usable. Strong framelock, micarta, smooth opening. It's not great, but certainly not junk.
Rough Rider's slip-joints also get quite a few good remarks on this site. I have one and really like it. I also have some of their other stuff. The fit and finish isn't the greatest, but for the price, the ones I have are not bad.
The only S&Ws I've handled are the KoA style cleavers, and they're one of my favorite cheap knives.
Frosts of Sweden (now merged with Erikksson) is a knife and tool making company based in Mora, Sweden. They're knives are very inexpensive (around $10.00) and are often referred to as Moras. They make many different styles ranging from small wood handled carving knives to large plastic handled butcher knives, as well as augers and drawknives. Frosts of Swedens (and Erikksson's) knives are the single best value in the knife world. I have several.
Again Frost and Frosts are two totally independant companies. And price is not an issue. Frosts of Sweden knives are usually cheaper than Frost cutlery knives, but you'd be hard pressed to find someone who would say that FoS knives are not a fantastic value.
I think I own a similar rubber handle serrated lockback folder, it's an EKA/Normark made in Mora, Sweden. Sharp as hell. Can't beat it, paid only 16 bucks. I also own a $ 15 huge Frost plastic handle chopper, it came with an unpolished blade from tempering. One of the sharpest blades I have
EKA also has nothing to do with Frost Cutlery. EKA is a Sweden based company that also makes really nice knives for the money. They mostly make folders, but also have some fixed blades. Is
this the knife you have Walt? Ragweed forge has them for $10.00. While I don't like serrated knives, I bet they're a great value. Also, is your chopper listed on
this page? If so, then it's a Frosts, not a Frost.
Now, back to the OP.
Both were given to me and I have been pleasantly surprised at their utility
I'm going to assume these are Frost Cutlery knives, since Frosts of Sweden doesn't make these kinds of knives. That said, if you like them, and they're holding up well for you, then don't let anyone else's opinion keep you from using them.
