Anyone care to speculate regarding late appearance of the Manix 2 at Deadwood?

Just some stock held back…?

I got the email. By the time I clicked (I was curious to see if it was an email glitch), it wasn’t in stock.

Couple folks on Facebook reported grabbing one, so it appears they had them. I got two emails with different time stamps for in stock 9:11 and 9:13 again, normally I never get an in stock email and this time I got 2 and still missed out! We've seen a few of these pop up in very low numbers at dealers lately and not just overseas. No idea what the story is. Normally Deadwood's prices are pretty high but $200 for a 15v Manix right now is a good deal.

Well...I order one. I missed all the first runs of the Manix in 15V. Just logged on to the forum and saw the post and went to their website. It was in stock for a few minutes and checked back and it was OOS...

I did receive an email invoice. Never ordered from Deadwood before, so time will tell. :thinking

I was able to snag one from Deadwood about 9:15 pm. I got a confirmation email as well. We'll see.

I think I got one earlier from Deadwood. 🤞 It will be the first 15V for me on this island. 🦘🇦🇺

impromptu home repair today required stripping a wire in a hard to reach place and all i had was my 15v manix. i was curious how it would handle the lateral pressure and the wire. here's a closeup of the damage. nothing too terrible, but it's definitely visible when looking real close. this isn't a complaint... just a data point.

Copper wire? Like Romex?

Factory edge is a hollow bevel at ~17dps.

Most folks see improvements to durability when the factory edge is removed to the angles they need, it also can introduce some convexing which can increase durability depending on the method used to sharpen.

i don't know what romex is, but it was a small gauge, solid core copper wire.

i haven't done any sharpening or touch ups yet because i haven't put the knife through any serious use until today, so this is still the factory edge. from what i've seen and read about this steel, i expected some damage. being used to softer steels, i don't usually see this kind of damage, but i did expect it to a degree. this is what happens when you use your knife for a job that has a its own specialized tool. i'm not upset or worried about it. it's barely even visible and i'm sure it won't be terrible to fix.

What other steels have you tried this sort of thing with?

I've found the damage from abusive cutting is heavily affected by edge geometry. The edge on the manix is quite thin from the factory, so most steels would have a challenge there. I have noticed K390 seems to survive abuse well even with a similarly thin edge though.

As an industrial electrician that strips every kind of wire with my spydercos in sprint steels, this is interesting to me but doesn't mean a lot since it's the factory edges. I almost always get light chipping on my factory edges. In particular I remember my rex45 getting several large ones on the factory edge but after a good hand sharpening, introducing some light convexing from freehand, and removing a fair amount of steel it's now extremely stable against copper.

I have some 15v coming to me and hope that it will be stable as well. If not, I'll just have to slowly steepen the apex geometry until it is.

It is interesting. Household copper wire isn't very hard. Romex BTW is the (often yellow or white) plastic clad multi solid core wire that runs through your house, where it's typically inaccessible (by code).

it was wire connecting the sensors for the garage door opener. the connection broke so i had to strip it back a little to make a new connection. really simple job, but it was an awkward position and i didn't have anything but my knife at the moment.

K390 is a great steel just tougher than 15V, it would roll rather than chip. 15V fills the void between K390 and Maxamet. BBB spoke very highly of K390, 15V gives up some toughness but gains edge retention.

Have you experienced this first hand?

Hardness is resistance to plastic deformation, including rolling. K390 is at 67 HRC which is incredibly hard. I have never had a steel that hard roll on me when stripping wire. In fact I don't see edges roll at all vs copper when they're heat treated well and past about 63 HRC. Toughness is in part resistance to chipping, but edge geometry also plays a huge role there. So it ends up being mostly about determining the lowest angle you can get stability out of, which is lower for steels with higher toughness and HRC combined that also have fine microstructure.

This is the exact opposite of my experience. I've found K390 to be extremely resistant to deformation, and more likely to chip when pushed beyond its limits. On the other hand, I've had 15V chip just a little and also deform just a little.

We have to remember, without having a measurement of the edge geometry it will be difficult for folks to use real world comparisons between steels.

A freehand 15dps is not 15dps and will convex near the apex and the factory 17dps is a hollow bevel.

Durability starts at 20 dps for all steels but cutting ability is reduced so its an inverse relationship that we have to choose.

I can confirm. I got a small chip rather than a roll in K390 when I hit a staple in cardboard (13 dps + 15 dps micro bevel). It sharpened out easily.

Looking forward to compare 15V with K390 and Maxamet, when a Manix arrives soon.

Seki K390 is super resilient, and well supported by the Stretch 2’s bladestock and thin behind the edge geometry. I remember having a hard time dulling one of my knives on a stone before sharpening.

I don’t think I have enough experience with my 15V manix or 15V PM2 to make a good comparison between K390 and 15V. (Only one and two sharpens in respectively on a fixed angle system). I definitely like the manix better as a cutter than the PM2 presently though.

15V moves much more easily on the stones than maxamet, and I’ve been able to do stuff like scrape tape from stainless steel sheets with only apex damage that you would need a microscope to
see (strops out easily). I still haven't gotten it as screaming sharp as I can for K390 but that is likely just my inexperience with the steel.
