Sandvik steels?

[Cliff Stamp]

You can grind full hard M2 and make a knife out of it, full hard AEB-L would be much easier in comparison. Since he is grinding after hardening, I would expect a high temper and fairly soft. I would be interested to know why he doesn't harden after he grinds the blade, aside from the knives he wants to make right in front of a customer.

I dunno, seems like a waste of belts.

Cliff, I think you need to find someone to teach you to make knives and buy some equipment. I'm not saying you will or won't be a magnificent knife maker, but it would change your thinking on certain things, teach you some others, and clear up some foggy subjects. BTW, that has nothing to do with your question.

The above comments on grinding M2 and AEB-L come origionally from Alvin Johnson who has made many knives out of full hard M2 and has ground Bos hardened stainless blades for comparison purposes which was much more high carbide than AEB-L. The stainless grinds way easier. You can read his comments on rec.knives in detail.

I have reprofiled a number of such steels and regrinding a high carbide steel like D2 is very difficult compared to low carbide steel like AEB-L so I agree with his perspective. This should be also be obvious because what you are doing is basically inverting the wear resistance.

As for the other comments, if you were grinding AEB-L after hardening then it would be difficult to do without exceeding the optimal temper which is likely 150-180C, and thus you would temper higher and thus it would be softer and thus easier and safer to grind.

about the prices. i think if youre in the US (or anywhere outside the EU) you dont have to pay taxes, (the taxes on products here is 20-25%, for example if i buy stuff from the US im not paying the US$ price x 7.3, im usually paying around x 10-10.5 because of the taxes) so in reality you will pay a little less for the steel.

ive tried to make knives out of hardenend hss and i wouldnt recommend it, i used an Al-oxide wheel/stone (white) but still it takes a long long time, not to mention drilling hss, its impossible without carbide drills or severely softening the hss with a torch (you need a real powerful one)

Legally, you are supposed to declare and pay import taxes.

That is a couple of hours, using an angle grinder and the right wheel. To drill the holes use a dremel and grind them out. The finishes knife looks like :

The good thing about HSS is that you can get the steel for essentially free as power hacksaw blades, the cost of heat treating is nothing and you get one of the best cutting steels possible.

im not sure we are talking about the same taxes, but im fairly certain it a little cheaper for people outside EU

Likely as you are paying a import duty not the full sales tax of the country of origion. When you import you also have to pay other fees like custom inspection, repackaging, etc. . These can be up to $50 which is why I usually avoid courier services because you can order something for $25 and then have $75 in shipping and fees. If these types of steels do actually catch on, which they should because there is a huge market for them, considering the amount of people who praise similar characteristics in low alloy carbon/tool steels. Then there is obviously a great chance for a US/Canadian maker to approach a steel manufacturer like Carpenter and just order a bunch of it and resell it to makers. It will really only take one maker to really aggressively promote the steel to start a fad movement, and in this case there is actual performance data to support it.

I think he maybe means the VAT or something, tax is already figured into the price for EU countries, not like the US, where the prce before tax is advertised. So you would pay less than the listed price for being outside the EU, but then you have to add the other fees on top.
