Hello,

The title says it, some sugestions pls. Which one is getting sharper and holds the edge better . The Lauri should be superior (63 HRC) than the mora (60-61) or am I mistaken? What steel grades are used in both?How do they compare to a rhombic forged silver steel blade?

Both are great. I prefer buying the Lauri PT blade blanks and making my own knives from them.

I don't think there is any issue of one being more "superior" to the other, just your preferences as to blade hardness. The Lauri PT is ~63HRC, and you can strop it to scary sharp, but the edge is more brittle as a result.

Mora carbon steel blade hardness is more like 55-58HRC, so may be easier to sharpen in the field. Once, on a whim, I stropped my Mora #1 to a true razor edge and shaved my face with it.

Both are rather inexpensive, so you can buy both and compare for yourself.
 
What about Mora Laminated blades? Or forged rhombic silversteel blades? I have one blank for each of them and cannot decide which one to keep for myself.Any insight?

No clue what a forged rhombic blade is, but why would it matter? These are relatively inexpensive blades with traditional "thinner" thicknesses. The Triflex is a laminated blade, probably a bit more flexible than the other two, but how much flex or bending do you plan to subject to your knives?

You are focusing on the wrong thing. You should determine what you want to cut, and base your knife decision based on this. You plan on carving wood, processing game, preparing meat, general chore usage? For most people, any of these knives would work well for you.

If you have corrosion issues, then go stainless, otherwise buy one of each and see how YOU like the blade edge properties of each. There is no wrong answer, it is all personal preferances.

They're arguably at the top of the puuko quality tree and usually cost several times more than the other blades mentioned. Rhomboids are usually hand forged from a special steel that takes a super sharp edge. The blade has a rhomboid cross section in that it narrows back in after the grind.

Oh, thanks! With that definition, I guess I have several of them! I collect puukkos and Scandi knives.

I did figure that they were probably of a different class than mass production knives like Mora & Lauri.
 
Laminated Mora is really something special in terms of sharpness. Helle does a nice laminate as well.

I think this is a good example:

The blade steel is called (not terribly imaginatively) "silversteel." And there is some intersection with what are called "tommi" puukkos. As far as I can work out, the "tommi" thing just means "This is a specially nice knife" and refers back to a Sheffield (UK) knife maker, whose Finnish pupil used the skills he had learned in industrial revolution England to make much better puukos when he returned home.
 
So, nice info here:) whats the sharpness and edge retention of these blades compared to laminated mora s or lauri PT s?
 
Silversteel currently used in Finland is Böhler K510. If properly forged it gets an extremely fine grain; it can also get high hardness (64-65 HRC) even thouth is normally tempered to lower hardness. It has a quite good resilience too, despite the high C content. It can get a very keen edge and holds it for very long.

Tommi puukkos took their name from Thomas Woodward, a Shieffield metallurgist, that made smithy courses in Fiskars around 1870s. Kalle Keränen, a karelian smith, went to his courses and together they applied oil quenching to puukko blades. Kalle later called his knives after his master's name.

Rhombic blades are actually way older than Tommis as first rhombic blades are signaled in late 1500 or at the beginning of 1600, though they could be even older. They were forged exploiting the geometry of square files.
Rhombic blades excell in wood carving and game dressing, the two porpouses they were born for.
 
Ussually rombic blades as someone said are the top of the line from Puukkos, however these are very hard blades ( meant for carving) so they can be on the brittle side.

Just depends on what you expect the blade to do. If you are carving ussually harder the blade the better, if you want a all round do it all blade the only rombic blade that is also tough in my opinion are Puronvarsi.

Moras are cheaper all round blades, the laminated are also more for carving. ( not the knid of knife to batton...in my opinion no puukko should be used for battoning, they are specialized tools...that is what a Ax or even a big blade are used for).

so basically my point is...if you are going to use your knife for carving and dont want to sharpenn your knife and dont mind spending more money, go for the rombic tommy puukko, if you want to spend more money on a beautiful blade and want more of a all rounded blade, go for the puronvarsi, if you do not want to spend much money on a carving knife Lauri pt of Mora laminated, if you want a all rounded knife and not willing to spend a lot of money, I would go for the lauri blade ( mora short tang gives you less capabilities on building a knife ( performance almost the same)
