I'm away from home right now, but will check over the weekend. I think the model number is stamped on the blade or something.

Again, I'm not bashing Moras. I'm not worshipping them either. They are a very good value for around $10 - $30. But a lot of folks claim that more expensive knives don't cut any better, and that is simply not true. Doziers, for example, cut much better, but are also more expensive.

As for the steels, much depends on the heat treat. 1095, for example, at the mid to upper 50's on the HRC scale, is a fair performer, edge holding on the lower end of acceptable for me. If you take the EXACT same steel, and heat treat it correctly up to 65 HRC, it truly becomes a super steel in terms of edge holding, bested by very few. It is incredible what range of capabilities this steel has.


When I said 20~25 I meant inclusive, at 10 per side D2 will not hold up nearly as well.

At 65HRC it's going to be too brittle, perhaps for a small slicing only folder but any field work will see the edge chip like ice.

I agree, 65 rc sounds way too brittle to be of much use, sounds like glass.

Wrong. The knife we used was measured at 65 and we cut sod with it. Actual results in the field can be very different from what you read. I'm only posting on my experience, not on what I've only read.

And my angles were inclusive as well.

I prefer a full flat grind with a thin edge bevel and a microbevel. It tends to cut much better than the Mora's saber grind


Different mora's have different grinds. My mora 511 certainly does. I am afraid I am not very good recognizing the different mora flavours, but I have one model with a saber grind and several with full flat grind.

I'd love to try the full flat ground ones, any more info on them? Thanks!


Sorry about the late reply, my knives were scattered all over the place...

I haven't been able to find out which of my mora knives that have the saber grind. All I know is that is one of the "modern" moras with plastic handle and it says "stainless steel". It looks somewhat similar to the venerable 860 clipper, but it's not.

My moras with flat grind are the 860 clipper (stainless), the 511 (carbon) and the 546 (stainless).

Been thinking about getting a Mora. I'd use it when out hiking and backpacking as a general utility knife but also as a survival knife in a pinch. Probably get the classic style with the red birch handle -- inexpensive so I won't be tempted to baby it.

So, guard or no guard? Seems like, especially when wet, one's hand could slip onto the blade with no guard, but the one with the guard seems like it'd be less secure in the sheath and that the sheath might not hold up as well under hard use since the sheath has a slit (to accommodate the hand guard) that extends about 1/3 of the way down the sheath.

Here, you can see the hand guard sticking out of the sheath:

Hi Jim,

The 2 similar Mora knives I have are gaurd-less. I once put my thumb on top of the blade thinking it was the back of the knife, no bad cut but sure got my attention. Three weeks ago I used both a standard "no-gaurd" Mora and a Mora Clipper to skin and butcher a deer. Both felt good in the hand but the standard wooden handle got a little slippery and I kept the thought that it was gaurd-less in the back of my mind.

I would next try one with a gaurd, I could always shortening it if I did not like the size or remove it all together if I wanted.

The carbon Mora I have gets sharp, but the laminated one gets really sharp! I do not know if you can get a laminated Mora with a handgaurd?

Later, Mike

Mike,

Interesting that you should mention the Clipper. That's the other Mora that I was looking at. I like the classic look of the ones with the red birch handle, but I keep thinking rubber is going to be more practical. The Clipper is so inexpensive I won't feel like I have to baby it. I have a SOG Field Pup, but it's such a beautiful knife that I haven't used it much. Dumb, I know, but it's hard for me to want to baton a work of art. The Clipper's nothing special and would make for a good knife that I won't be shy about using. The Clipper's weight is also pretty attractive.

Thanks for your thoughts,

HJ

Hey Jim,

I have used a Mora Clipper a lot and really like it, I use it much more than the traditional oval wood handled Mora.

Mora recently came out with a knife similar to the Clipper but with a slightly thicker blade and grip, it was called the Craftsman Allaround but I think it is now called the Top Q (SS) or High Q (Carbon steel). I have used the stainless version and it does feel a little stronger than a regular clipper.

Both versions can be seen at Workwear Canada along with a short video by owner Paul Robinson.

I am sure they are available in many places in the US also (Ragweed Forge?).

Very high quality, functional knives for the price.

I know what you mean about a knife being too nice to use, I have a first run Dave Canterbury/Blind Horse Pathfinder Knife that I cannot bring myself to take in the bush.

I have started carrying a very nice Fallkniven F1 though.

No ownership in any of these businesses ...yada, yada, yada; just a happy customer.

Good Luck, Mike

i think Mike made a good point about whats so great about Mora knives,they are not so fancy and expensive that your afraid to use/loose them.
