Probably not. Knife collectors are all about special super steels with >60 HRC blades, something you can’t do in your garage.

If you git gud with the homemade ones and they look nice, you can try to sell em on Etsy for some money, bonus if you get a youtube following. Either way, the slim chances of making profit is a few years down the line, lots of trial and error first.

>>1998255
The money is in the youtube revenue, not the selling of the knives.

>>1998267
that makes sense.
Getting people watching how the knife gets made actually helps them make more money than selling the knives themselves.

>>1998269
As a bonus, you could probably sell the knives to your viewers for more than any logical person would pay for a knife some random person made in their basement.

>>1998278
Then become a Youtube star, design a knife for Gerber or Kershaw, get your name stamped on it, become a sellout and laugh all the way to the bank.

It's a butterfly knife.

>>1998451
Protip: do not practice with butterfly knives while barefoot.

Trust me.

>Is there a lot of money in in this kind of thing?
None, the chinese have you beat in every single way
The only money is ultra high end with ultra high end materials, and even then its a popularity contest filled with politics from snobs.

Do it as a hobby, not for profit. If tou get good and recognized you might be able to charge some money for them but your fist bunch will be absolute dog shit and the next bunch mediocre at best. Between the investment in tools and time you'll make nothing

>>1998558
Also this, dont sharpen knives barefoot either

>>1998265
FWIW you could try to find some heavy duty industrial junk like I don't know, old locomotive steam valve, and claim that that steel is very rare and special and spin a legend around it.

>>1998734
Id tell you to stfu but realistically, it would work

If anyone knows about knives can you answer this please?

Its quite easy to get a convex grind on if you have a belt sander though since you have to ask, I'd say you save yourself having to get a belt sander by having a professional do it.

>>1998255
Nah, as other people said- its ad-bucks from youtube
Which is sort of a value add to time spent making and the time spent producing the video so I don't really see it at being facetious in any way, even if I think the knife is shite, steel is garbage and their technique is rubbish as long as its providing interest and maybe inspiring someone else to do better.

You can sell knives and make money, I rattle off about 10 a month which is a mix of the mid-upper kitchen knives and once in a while I'll make something fairly artsy-exotic piece which is a bit more. Mostly to the professional chefs and home users that want something good. The other half is the 100-150 range smaller stuff, paring knives, the occasional petty which is a good way of making cash as they're generally a lot better looking and cutting than a cheap kitchen knife but your material costs are quite low. You should be able to knock out about 2 dozen from something like a 3-400 plate of mill ground, mid-high end stainless.
Smaller knives can be a bit of a time sink though and its really all about doing things in batches, making sure your efficient with your time as the overall material cost is generally not too bad if you go big on your supplies. Abrasives will be your big spend though, belts are expensive but quick, sandpaper is cheap but takes longer- so its just a case of finding the right mix to suit your budget

I was just worried it would over heat.

>>2001055
Get a bit of cloth, masking tape it over the handle to protect the finish, then do maybe 2 passes- cool it in water, 2 passes on the other side and cool then repeat until sharp. If you're a bit gung ho with pressure it can heat up quick but keep the passes quick, even, same angle of presenting it and light pressure and it'll be fine. If you're worried about the blade finish you can tape up the areas outside the secondary bevel with a couple of layers of painters tape.

>>2001062
Thanks. That will really help.

coils, checking the coils is the equivalent of turning it off and on again. Do that first always.

It's called corner bead. Definitely watch some videos on drywall and mudding. It's not hard to do an ok job, and at the worst you just sand it all down and do it again.

any EMT electricians here? Can i use these in a tight corner instead of a 90" pipe bend? i know these are used when you have more than 4 90's in a run but is there anything with only using these?

I'm also looking into knifemaking.

Just finishing my law studies but I am realizing that I probably can't spend my life doing stupid 9 to 5 white collar shit.I am lucky to live somewhere other than America so I don't have too much student debt at least.

I am planning to start practicing law while taking classes and visiting masters of the craft, and opening shop when I have enough money and skills in my 30s.

>>1998591
I go out of my way to buy non Chinese products and would be happy to buy something hand made and locally produced.

>>1998663
also this, dont throw knives barefoot either.

>>1998255
It's all ad money. They usually just give away the knife to the viewers

That's a Scottish sgian dubh patterned knife, but unless you paid a LOT of money for it (upwards of several hundred dollars) that is definitely not real damascus steel. Any grinding you do will take that pattern right off of the blade.

If I'm understanding you correctly, is the blade literally a flat, triangular shaped bar of steel with no bevels at all?

>>2003333
There's a fairly low entry point- small anvil or anvil shaped object, machinists vice, clamps, decent hammers, tongs, 2-4 brick forge, propane burner, files, sandpaper, quench bucket and maybe a 1x30 grinder or 4x36 + disc grinder, 4-5" angle grinder, cheap drill press or good corded drill
The rest is mostly just timbers, G10, some bolster material maybe and a few bars of 1075, 1084 or 80CRV2 and tempering can be done in a basic oven. Realistically you're probably coming in at around the $6-800 mark for most of it. Even expensive things like a good hammer you buy a 2lb lump hammer, re-surface on a grinder to suit.

>something you can’t do in your garage.
You can if you got the money. My buddie who owns Helms forge can get 60HRC, he works out of his garage.

>>2006669
I work out of my garage as well, these little buggers are 65HRC, very high purity carbon steel and you're only looking at a 10min soak at 810C
Majority of my stuff is stainless though which usually in the 58-59HRC, semi-stainless is in the 61-62HRC. That does require a kiln + thermocouple though which isn't always available but there's also nothing to stop you shipping them off to a heat treat place or someone else who does have a kiln or if you're feeling adventurous you can do it in a blocked off forge and carefully maintaining your temps manually. You can get a K or N-type thermocouple and reader for about $50-100 with a bit of shopping around and I recommend most people do that instead if staring into a pit of infrared radiation and 'guessing' how hot something is.

Peak hardness isn't everything through unless its suitable for the knife and given a lot of people are clowns with knives so its often better to trade off some of that for a bit of toughness in case it ever gets used as a pry bar, popping the lids off paint cans, thrown at a walls, dropped on the floor, being whacked on the spine and other chimp levels of abuse.
Its why a lot of outdoor knives end up in the 55-58HRC bracket because people try to cut down trees with them

so is sv30 the quintessential outdoor knife steel (hunting-skinning/fishing/utility) or would it be better to make each of a different alloy? A lot of my research is showing that sv30 is a pretty top end all-rounder but then isee shit like s60v, s90v, d2, etc. and start getting confused. I know "best" is subjective but i would like to make a 3blade outdoor set.

>>1998265
In that case you would gain more money by Youtube revenue than by selling the stuff you make.
If you take that route, offer the stuff you end up making as Patreon subscription prizes.

>>2008113
S30 and S35 are both really very good steels for making a dedicated cutter and slicer out of, its in the higher cost for material and benefits from an exacting heat treat. There's a few others in the really-high price bracket like M390 and Vanax which are excellent steels and only slightly better.
But on an apples to apples comparison, its pretty minimal that the average user would be able to tell much of a difference between them in terms of edge holding and stain resistance. You won't really go wrong with a well heat treated bit of S30V

>>2008137
Good to know. I plan on making a good handful of outdoors knives as well as possibly some kitchen knives so was hoping to find one alloy that I could just buy a bar of a single alloy for my next batch of projects. I was also looking at m390, supposedly its a bit easier to sharpen. I'm fairly new to actually buying alloys. I usually practice or make shit with random scrap pieces or very common stuff. Are s30v or m390 relatively easy to find at any metal supply shop or are they specialty pieces that have to be ordered?

>>2008139
S30 seems to be around relatively often, its often pricey though so I've not had much to do a batch with. M390 can be scarce in large amounts as well and it's a very expensive steel. At the moment I don't think I can hit the critical temps on it with my equipment well enough to warrant the overhead costs so I've shied away from getting it.
(My large amounts I mean plate-stock of about 20-30cm x 1m long)
You can usually get in strip of 1-2" by 1yard or 1m depending, I think Alpha carries it in the US, Groundflatstock in the UK carries some S30 and S35 and Artisan supplies in Australia carries M390 but I think theyre our of S30
