Já ty klobouky normálně opaluju nad plamenem. Je to pak takový mix modrošedohnědožlutočerveno atd.
Dělám to vždycky, protože přesně, nemám rád jak se to leskne.
Nemůže se to hlavně přehnat, ale zatím sem nikdy nezaznamenal zhoršení funkčnosti šroubku:)

Tady bych se bál, že ty šroubky změknou.

Ahoj skúšal som to a nedoporučujem ,čierna to nebude iba trošku stmavnú.

Mantra a buttonup tvarově moc hezký, akorát ten materiál čepele...

Nj, mantra na položkách a v nejakej práškovke a mal by som favorita. Inak asi nič zaujímavé.

Je vidět, že šlápli do těch low endů, aby dokázali trochu konkurovat Číně. Mantra pěkná, ButtonUp taky. Osobně bych šel tak do Bodaciouse ve sprint runu.

Nový přírůstek...

Gratulujem 😇
To je skvelý ľahký EDC nôž v brutálne dobrej oceli, ktorá sa navyše už viac nebude vyrábať.
Keby som už nemal 15V doma na inom modeli, hneď si ho kúpim tiež 🫣

Ci sa bude alebo nebude vyrabat je trosku vestenie.. Ale je fakt ze koli konkurznemu konaniu s Crucible Industries som si uz aktualne nadobudol 3 Spyderca s 15V a TrippleB teplenym spracovanim Big Brown Bear sa naozaj predviedol v tom najlepsom svetle.

Žiadne veštenie. Crucible je minulosť a zvyšky si rozobrali supy😱
Oceľ 15V vyžaduje extrémne vysoké teploty pri výrobnom procese a nový majiteľ nechce do takej technológie investovať.
Našťastie Spyderco nakúpili zásoby a vyrobili parádne limitky. Ešte sľúbili vyrobiť nôž v designu BBB a potom koniec 15V 😓

Zaujimave porovnanie drzania ostria. Celkom ma prekvapilo ze 15V prekonalo aj maxamet, v drzani ostria.

vid 9:50 pekny graf s porovnanim https://www.youtube.com/watch?v=d1hUQYP96AU

CPM 15V je spíš kuriozita než cokoli jiného.

Ve své podstatě je to slepá větev vývoje oceli CPM 10V.
15V má sice o 16% lepší retenci ostří než 10V ale houževnatost šla na půlku.
A to za cenu technologicky složitějšího, dražšího výrobního procesu.

Shawn Houston (BBB) využívá primární tvrdosti při svém tepelné zpracování.
Díky tomu má jeho 15V o trochu lepší houževnatost. Jenže na úkor retence ostří.

Z pohledu vlastností, užitné hodnoty a ceny je 15V v dnešní době již překonaná ocel.
Například ocel Z-max nabízí vyšší tvrdost i houževnatost při nepatrně vyšší retenci ostří.
Naopak bestie jako Rex121 nabízí o level vyšší retenci ostří než 15V.

Přesto ale platí že 15V je velmi zajímavá ocel pro sběratele a to hlavně díky ukončení výroby -> limitovanému množství.

Fanoušci hi-end ocelí nemusí po CPM 15V smutnit.
Nové a vzrušující oceli se objevují každou chvíli.
V poslední době třeba MagnaMax, Zapp Z-12 Ultra či SPG Strix.

Myslím že trochu zavádzaš. Najprv porovnaš výdrž ostria / húževnatosť medzi 10V a 15V. Čo by asi tak približne sedelo. A potom ako príklad uvedieš Z-max a Rex 121 ako ocele s lepšou výdržou ostria ale už akosi zabúdaš spomenúť že obidve majú mizerznú húževnatosť 🤨 Takže tvrdiť že sú "lepšie" ako 15V je diskutabilné. Ako hovorí Sal Glesser. All good, but different 😋

Z12 ultra je len verzia Magnacutu. Ako aj väčšina Zapp oceli sú v podstate len skopírované recepty🥶
Magnamax možno bude zaujímavý a SPG Sprig sa uvidí 🤔

It's not without merit.

Firstly, you gotta understand that 15V is from the realm of "tool steel". That basically means steel that's used to create cutting bits for mills, lathes, etc. in precision machining. In other words, it's steel that cuts other steel. A lot of the predecessors to the A11 type of tool steels (of which 15V is derived from) were meant to stay hard through high-temperature/high-speed work. T15 for example, used vanadium as well as molybdenum and tungsten in order to achieve very high wear resistance, and to keep hardness through heat. T15 is more of a direct predecessor of Maxamet, but Crucible realized sometime in the 1970s that they could use vanadium alone to achieve a tool steel that could be a carbide-replacement suitable for cold-work applications. Afterwards AISI classified any steel with ~10%-11% vanadium as A11, but for the most part compositions became very brittle at 11% or greater until Crucible discovered that they could increase the temperature of the melt to very high levels in order to get above that level. Evidently they even developed 18V and 20V (not to be confused with 20CV), but never produced it--probably because there wasn't much economic value in it when producing 15V was already very expensive and the modest improvement of 18V and 20V wouldn't generate enough sales to offset the increased manufacturing costs needed for temperatures high enough to melt it. That's a lot of background information, but the important piece to keep in mind is that it was only ever designed and marketed as a replacement for carbide tool bits, and was particularly difficult to manufacture with arguably diminishing returns on investment over something like their 10V.

If you want to dive deep into that, Larrin Thomas covers it all in his articles about it:

https://knifesteelnerds.com/2021/05/24/cpm-15v-and-the-lost-cpm-20v-how-much-vanadium-can-you-add/

One of the things explored in that article is Crucible's recommended heat treat protocol. As I mentioned above, they were really marketing and designing it more as a carbide-replacement tool-steel and so the heat treatment they specified to use didn't really maximize the characteristics that would be more desirable as a cutlery steel. Larrin Thomas covers it in detail in the aforementioned article, but essentially Crucible's protocol maximized toughness and work-hardening characteristics that would only become apparent in machine-tech applications. When custom knife makers made blades with it and followed Crucible's specifications and used it as cutlery steel, it didn't really offer that much better performance over 10V in terms of edge retention, while it was less tough, harder to grind and more expensive to purchase. In other words it seemed like vanadium-rich tool steel stopped making sense as cutlery steel once it got beyond A11 levels, and so there were a lot of steels developed targeting that composition and even new ones like Vanadis 8 and 10 as well as K390 developed as improvements with other alloying elements, while 15V kind of just sat there without anyone trying to develop cutlery with it for a while.

That is when Shawn Houston (aka BBB) started to play around with 15V and developed a heat treat for it that would maximize edge strength for cutlery uses. He talks about how M4 and K390 really lead him to realizing that very high Rockwell hardness levels were being avoided in cutlery, but that it was unnecessarily so as even extremely hard steels that should be "brittle" when you look at them on paper were making knives that were extremely capable of offering the strength needed not to chip or break while also offering very high levels of edge wear resistance while doing it. More importantly, they held "front end" sharpness better than most of the available offerings like the S90V and S110V types of steels which seemed to lose initial edge keenness quickly even though they held a working edge for quite a while.

You can hear him talk about this in his own words in this video:

https://youtu.be/l0hG2DqGZLI?si=CJyibTXY0VCQ0CE1

There's also a thread on Spyderco's forums following the development of his custom heat treat, and when Sal Glesser decided to collaborate with him to implement his best treatment protocol into a line of 15V Spyderco knives. Despite literally monumentous setbacks like the COVID-19 pandemic, it all managed to come to fruition with the first releases of the Mule and the G10 Manix 2 in 2022.

https://forum.spyderco.com/viewtopic.php?t=82056

The models we're seeing coming down the chute now were announced a couple years ago, and unfortunately since then Crucible has announced bankruptcy so there's some question about whether 15V will be produced again. Many companies have announced that they will buy the rights to produce many of Crucible's more popular offerings, but so far nobody has said anything about 15V. There is some speculation that no other foundries even can produce 15V due to the higher heat needed to get that level of vanadium, but I don't think those assumptions are necessarily well-founded. The more likely circumstance is that no foundry will find that it makes economic sense to produce it, since many might not be set up to be able to do so without significant investment. Companies like Bohler that are currently producing K294 and K390 are probably the most likely to be able to get their factory set up to produce 15V, but they're not exactly geared towards producing steel for the cutlery industry. Really, most aren't, as cutlery-industry consumers are a very small segment of the market that steel companies service, and tool steels aren't used by many knife manufacturers in the first place. It would be a bit like planning to sell aircraft-grade aluminum parts to car-parts stores.

To sum all of that up: It's an extremely high-performance tool steel that required a custom maker to develop a practical heat treatment protocol to be implemented by a knife company that even invests in offering its customers something like that. Then on top of that, it might not even be a steel that's produced again at all, and even if it is, the production of a line of models utilizing it can take years, likely not even with the custom-level heat treatment from BBB. It's basically three layers of specialty, fleeting availability and extreme levels of performance.

Chci se zeptat, tuhá pojistka na Manix 2 se rozchodí?

Ahoj skôr by som povedal ,že si prsty zvyknú🤣pamätam sa na tú bolesť ...Nie podľa mňa nie aspoň nie moc badatelne niekto si odstrihne jeden závit z pružinky to som skúšal ale moc som to nepocítil.Časom si zvykneš manix je fajn nôž.

Farebná postupka
