Heat treating is one process we will outsource initially. We could heat treat ourselves but have a company here in Thailand that we already use in aerospace and they are very good and can test each blade for hardness
I'm not a knife maker, but I'd still intentionally break few blades here and there to see the grain structure.
Want to make knives I would want to buy
If I wanted to just start a business, Aerospace has much more $$$
cheers
I see you on that point.
I would like to point out that as others said, to have someone spend $400 on your work - you'll have to build a name and reputation first.
If I was going into that business, first thing I'd do would be fixed blades in simple stainless and simple carbon steels, that's easy to heat treat, affordable and pretty much proven over the years, but I'd use different design to attract people to buy my product.
At the same time, you can hold a premium line too, where you're taking custom orders, using better steels, materials, better fit and finish and so on. Because if I'm about to pay over $400 for a single knife,
I have to be sure that you know what you're doing. And that can't be made over night.
I get it that cheaper or entry level knives aren't your thing, and you aren't doing this for money, but you'll still need something to stay afloat.
My advice is to get some Sandvik (or even AUS), D2 and something in carbon (SK5, 1095 or 80CrV2) and make some knives out of that for start. Those aren't super steels, but that's what majority of people can afford, and that's what is a person on a market for a new knife most likely to buy. And these steels have been proven over years of use. For example D2 and 1095 have been around since WWII, they're affordable and people know what they're getting. Not to mention that there's lots of people praising these steels, and also - people are more likely to buy something familiar to them.
