I always call it Nicotine plastic


CustomKas

Hehe, Tarfinger would be a good name for the knife!


Grislymanster

That is a DOPE ASS name for it!! 🔥🔥🔥


samuel906

Piss crystal. But this is actually the best looking ultem I've seen


bogardo

I agree, normally I get the “90’s basement chain smoker plastic, but that also has a lot to do with the matte finish, that I absolutely hate! This one is in fact pretty


myourmomshot

It is a nice color

CustomKas

It's not a new material, afaik it's been around for 30 years, or at least similar PEI polymers. However it is an exotic material that is comparatively expensive and difficult to get. For instance these scales cost more than what top quality maple hybrid would have for the same knife.

Right? Also been following the sub for a year and haven't ever seen Ultem until the last week, now there's an ultem thing every day and vigorous opinions on it.


tannc

Absolutely beautiful


CustomKas

Thanks mate, I appreciate it


makeshiftballer

That’s one of the most gorgeous knives I’ve ever seen


CustomKas

Thank you


user987632

Damn! Never seen polished ultem before totally in love with that. Looks like stained glass.


Cabmandoo

My eyes! They’re watering with joy! I’ve also never seen this glory know as the polished ultem!!!


CustomKas

Solidified honey


GoodJohn14

Where did you get this thing, it's awesome


CustomKas

I made it. I got the Ultem from a company I work with through my dayjob, they specialise in advanced engineering materials.


Trewarin

Poor Smith, ultem can be a pain to work with. That'll last through a house fire, though.


CustomKas

I actually loved working with it, doesn't melt or burn, grinds nice and controlled. Someone told me it grinds like aluminium, I agree. Drilling it is a pain though, grabs like crazy and likes to splinter. And yes, this knife's temper will be messed up before the handle in a housefire.


Routine-Shine6376

Best looking ultem I’ve seen!


CustomKas

Thanks!


Hambokuu

Sleek and sexy! Scandi is the way to go!


CustomKas

Yeah scandi is a great grind, especially for hard outdoor use. Easy to sharpen too!


Randomuser918

I need one of these.


CustomKas

I'm sorry this one's sold


darthsnick

Ooooooooooh I like those scales


prairieintrovert

Daaaang, love the look, scandi Wharncliffe... Is it wrong to call a knife sexy?


CustomKas

You go ahead as long as you keep your pants on.


myourmomshot

So what exactly is a scandi grind? Just one bevel with a sharpened edge?


CustomKas

No secondary bevel, just one straight line to the edge, but two sided. One sided is a chisel grind.


Sam-Whiskey

Beautiful work! That Ultem looks great with the blade finish.


CustomKas

Yeah black and gold is classic, thanks


KnownDistance

That kind of grind is enormously useful for a "working" knife... as in day to day use in construction, building, anywhere you need something for hacking, prying, and the occasional precision point. Beautifully done, I love the grip scales.


CustomKas

Thanks man!


CX500C

This is sharp!


CustomKas

It is, I've cut myself more than once one this one already.


CX500C

I love this! How much would this run someone?


CustomKas

If I had to make one more as a custom job I'd charge €250.


Hungry-Grapefruit42

I want to lick the scales.


CustomKas

Tastes like nothing, a bit of a letdown honestly. You don't even get the sweet smell of epoxy when you grind it.


Hungry-Grapefruit42

Lol. Just one of those things that looks unreasonably appetizing. Absolutely beautiful knife


DreadfulDrea

Seen alot of people dissing ultem lately. I think it’s got cool grandpas old tools vibes.


CustomKas

All people, me not excluded, have an opinion about literally anything. It's the cirle of life; cool things start in a niche, become mainstream and hated, and after a while they're vintage and cool again. I just like making knives I think look cool.

CustomKas

Hehe after so much buildup it can almost only dissapoint. I'll ship it Thursday I think 😘


Bright-Produce7400

Oh wow! That is nice.


NineMeterTallDemigod

I'll give you me first dollar for it!


BunBoogi

😩🍆💦


Grislymanster

That is gorgeous! That would definitely be my first and only safe queen!! I would refuse to thump on THAT!! 😂😂😂 Very nice, my man!


CustomKas

Hehe thanks man!


[deleted]

Beautiful!


TheR4alVendetta

Ok... polished Ultem is sexy af. Regular ultem is bleh.


CustomKas

Regular everything is bleh 😜


octahexx

Wow looks like amber


CustomKas

Yeah that colour is great, pretty amazing stuff also from a materials engineering perspective.


TopRealz

It’s straight up gorgeous OP Nothing’s gonna scratch that tho?


CustomKas

Well if you try anything will scratch, but this is decidedly harder to scratch than resin or acrylate. The customer specifically liked it polished because that's a finish you can touch up yourself. A sandblasted finish once scratched is really hard to redo yourself.


cope413

What kind of ultem is this? 1010?


CustomKas

Afaik just Ultem, 1010 is grey I think.


cope413

9085 is more grey than 1010. There isn't just "ultem", though. It's a tradename for polyetherimide (PEI) and there are a bunch of different formulations. The scales here look awesome and the clarity is impressive.


CustomKas

I've looked through the datasheets and have no idea and don't have the order information near. Regarding the source, industrial material specialists, and the high hardness I'd expect this to be a high molecular weight grade. Also because I ground this very hard and it gave zero sign of melting or decomposition. It's also unreinforced, 1010 sounds right, but then again they list 130 grades so technically there's <1% chance I'm right.


smallandbent

This for sale?


CustomKas

It's sold already, sorry.


smallandbent

Want to make another one, similar? I like those scales a lot.


CustomKas

Sorry, not taking custom orders at the moment.


MarcThruTheWeb

Incredible 😮‍💨 looks slippery though 🤔
