Buck 110 in Bos 5160

[Navod]

I am still interested to know what type of edge retention we can expect from this 5160 spring steel. I called customer service to inquire what Rockwell hardness they used on the blades for the 110 and the customer rep was not aware of the 5160 order. She is calling me back with the information. Once we know the Rockwell it will be easier to know somewhat about edge retention. She just called me back and said the Rockwell is 58-60. Whoa baby! That is some hard stuff! That should take away from the toughness; now what about edge retention?

I'm not sure if you understand the difference between elastic deformation and plastic deformation.

To explain it more simple 52100 has higher flexibility than 3V but 3V has higher range of deformation yield before it completely broke.

Now were on the same page lol I have first hand experience with both steels, I broke a 52-100 blade doing a stupid task (prying) I happen to have a 3v knife in similar thickness and geometry (both are ffg) that survived the same exact task.

Not scientific I know, but it left me with the impression 3v takes more lateral force without failure.

52-100 quite likely might bend further than 3v but once again I prefer a knife that DOES NOT bend.

I'm not sure exactly how close 52-100 is to 3v in impact toughness or edge stability but I give 3v the nod.

And oddly enough my blade in 52-100 was 58 rc and didn't bend very far before snapping, could be an issue with the steel.

May be I choose the wrong word, my English is not very great.

52100 has higher range of elasticity, the range that it will back to true via bending even at 61HRC it clearly still has proper springiness. It will chip off when chopping something very hard like nail. In my opinion 52100 is better steel in very thin knife like fillet or razor.

3V from my experience doesn't has the flexibility like 52100, I don' know how to explain the importance of flexibility to the edge due to my language limitation but it does has a importance role.

3V from data sheet will take more energy before it break thought. In a waki to chop down a tree type of blade, 3V will definitely a better steel than 52100.

I never try to breaking any 3V piece my self but next week I will do some abuse test against D2, SK4 and 52100 in the same blade shape.

I agree on 52-100 being an excellent steel for thin blades, huntsman knife co a maker here on bladeforums did a run of woods machetes in 52-100 and displayed how flexible 52-100 in his machete is, I was IMPRESSED to say the least.

Different steels for different purposes, no one steel will be best at everything.

Im interested in your test results, I wish you had a blade of 3v to throw in the testing as well.

Sorry for coming off so strong, sometimes im too quick on the keyboard and its difficult to discern what exactly someone is trying to say over typed letters.

Ill read up on the importance of flexibility in the edge, I'm always willing/wanting to learn something new especially about steel and knives.

Hey guys,I found out some more info on the 5160 110's from Bucks customer rep. She just called me back a second time. ( they are serious about their customer service.) The first 100 of each in charcoal and oak will be serialized. If the vendor does a future order they will not be. Hope this info helps. I really enjoyed reading all the responses to this thread!

I have the 7 piece of CPM-3V blade going to be finished soon. This will be heat treat by one of the best HT equipment for knife blade in my country, very precise electric kiln with molten salt quench and double cryo. Molten salt temper too.

Actually I have one finished blade made from the leftover piece but it was HT by my friend with only plate quench and sub-zero. I have done some robe cut test and edge flex test with it but need to be pause becuz it still don't have handle installed and pain to use.

This is the pic of pic right of the water jet cut.

The raw piece of steel plus shipping and tax cost me $250

Damn, how much does it cost to buy European steel of the same quality?

That blade shape is very similar to my favorite knife, the winkler belt knife TAD edition in cpm 3v steel, comes with tapered tang and is EXTREMELY well balanced and ultra comfortable in hand.

And DAMN what size is the sheet that costs 250?

 

[shqxk]

There are only one type of powdered steel sold here, TSP4 which are equivalence to CPM-M4 and it come only in round stock so can't make use of it.

4" x 18" x 0.290"

In fact I ordered 0.25" thickness but it fortunately came oversized

 

[shinyedges]

Nice, that stock did look very thick. taper the tang on that beauty!!

4" x 18" x 0.290"

[shqxk]

My friend said its look quite similar to Winkler's Belt knife too, unless it will be sabre grind and has fuller This is wood model.

 

[shinyedges]

very nice, the high saber with fuller makes it look mean. What ever you do it will be tough as hell at .29 thick 3v.. when it gets done post it up for us 2 see, what handle material are going to use?

 

[shqxk]

Thank for the compliment!

I'm lucky that the maker who going to grind this is very specialize on cutting competition type of blade which has thick spine but very thin edge. I'm not a knife maker my self but I love to work some fun project with them.

The handle going to be green micarta with carbon fiber liner, 6AL4V pin and G-Flex epoxy from USAKNIFEMAKER site.

 

[shinyedges]

Excellent choice in handle material as well.. should be quite handsome with the carbon fiber liner, and Micarta always feels good in hand. I'm a little jealous haha

In the case of mr. bensinger I am curious what size blades he took up to 60 rc and how hard they were tested.

Regular old destruction testing would reveal a lot I think in this instance.

Everything up to 12-13" JEST bolos and bowies. And they have been tested to destruction, including the ABS 90 degree bend. (Disclaimer: not an ABS member)
This one was my personal bolo and is on its second owner:
It's got about 5 years of fairly heavy use. High convex grind.
This one I made for my daughter, who beats the living snot out of it:
Mine's about 9", the sinampaloc is about 13" in the blade.
All that being said, if you said "we want to make you a Buck 110", I probably wouldn't say "5160 please".
Although edge hardened it wouldn't be bad...

 

[shinyedges]

Impressive, they look well used too. First ive seen 5160 at 60rc in a blade that size. How is edge stability and edge retention compared to other typical chopper steels?

Also how did the D testing go at 60rc compared to other steels you have D tested at the same hardness? any chance you have done D tests on 3v or z wear?

I would love to know how they held up.

 

[bodog]

I really like the handle shape of the one you made for your daughter. Looks extremely comfortable and reliable.

 

[Duane Sanders]

Fairly knives has a S7 knife for the same prices as 3V knives. I really like the design and the thickness is more my style. To me 3/16" is fat. Their blade is "thinner" than a 5/32" I really like but if it's as tough as they say it should be fine.

I might have to look into that one more.
