Never touched a Mora I didn't like. I have the No 1, Companion, 2/0, Fishing Comfort, and Bushcraft Black.
I love the good ol no 1 for most tasks. It's light enough to wear effortlessly around my neck. It also cuts like a laser.
The real beauty is the ease of maintaining the edge. The combination of scandi grind and carbon steel means I can sharpen my Moras effectively on literally any stone I have around the house. Diamond, Arkansas, SC etc... They also respond and maintain very well on a leather strop.
The Bushcraft Black is as heavy a blade as I could ever imagine needing. Truth is, I enjoy owning that knife, but rarely use it. The no 1 is just so darn easy to neck carry. I rarely head out of the city and feel I need more knife than the no 1. The Bushcraft is capable of a lot more than I actually need. I scored a really nice, custom leather sheath for it a while back. It adds a little flair the plastic sheath was lacking.
The Companion is another favorite. I generally only choose it over the no 1 when I need the no slip grip, mainly when hunting. Blood and and fat make for some slippery hands and the smooth wood handle of the no 1, while comfortable, can be slippery in those conditions.
The 2/0 is a great little knife as well, though its very small. I wear it when I don't foresee much knife use needed, but still want the connivence of a fixed blade around my neck. It is surprisingly capable despite its size and in a pinch could still be counted on for some serious use. I don't do any lightweight, ling range backpacking anymore, but I throw it in my pack as a backup when I head out for a day or weekend.
The fillet knife is very capable, but its shorts length limits its use to fish no larger than about three pounds. The grip is the familiar grip of the Companion and the stainless blade performs well. Nothing much more to say about it.
The best thing about Moras is the price. Excluding the Bushcraft Black, they are all $20 or less knives. There is literally no reason not to atleast try one out. If it works for your needs then it will save you money over a more expensive knife. If not then it will still function as a backup knife left in your truck, boat, pack, or cargo compartment on your 4 wheeler.
The truth about Moras is they just bore the average knife enthusiasts. The are very good at cutting things, but lack the flair that makes owning custom and overbuilt survival knives fun to own and use. As for me, I choose to spend the extra money on socks and boots. I find I get more benefit in the woods from a pair of boots that are well made and well fitting while being waterproof, lightweight, and well insulated than having a heavy, overbuilt knife with all the bells and whistles. I have never battoned my knives, and never plan to. I have a knife (BK9) I bought just for chopping and batoning if I feel the need to. And guess what...it gets left behind on almost every outing. I have only played with it, never used it. Battoning is just not a requirement for me, and personally I would not recommend it for any of the Moras, even the Bushcraft Black. I really enjoy the BK9, its just to hard to make room for it. I am not a "bush crafter" despite being a member of the forum. When I head into the woods its usually for a fishing or hunting trip, or a day hike or camp with the family. I just don't need or have room for that kind of knife.
My next move is to buy some blade blanks and try to make my own Mora. I have a beautiful antler rack I cut off a buck I killed last year. I plan to make my antler handled Mora this fall.
I actually have never handled the Pro C like you have. I imagine it works as well as the other Moras. I also have never owned a SS Mora except for the fillet knife. I keep planning to pick up a SS knife to try out, but I have had not any real problems with corrosion in the carbon steel models. But for the price, its not a big investment to settle my curiosity.
