    In this video I talk about a very similar issue with a forged blade which is due to it being a shallow edge quench :

    I don't know who said that but they might not want to talk much about steels. If the sword/knife bends and returns back to true means it is in the elastic range (enough of it anyway). If this happens...

    As an aside, if you will bend it depends on how much side force you exert in cutting. People use very weak blades all the time and don't constantly snap them off, utility knives commonly have very...

    I did some work on the medium/fine stones awhile ago to estimate the grit finish they produce and measured it in a few different ways. The UF one is about twice as fine as the fine and like the fine...

    VG-10 isn't likely to be a good clad for Super Blue because they harden very differently. SuperBlue is going to want a lower/shorter soak than VG-10 and a MUCH faster quench. Plus VG-10 has many...

    420J1 is a lower carbon version of that class of steel, it is weaker and less abrasion resistant than 420J2. It is in fact so weak that if you are not used to that kind of knife you could even bend...

    CBN is not a new abrasive, it has been around for ~50 years, it is just a particular form of boron nitride. It is only recently (in the last decade) that it has been able to be produced with enough...

    1095 doesn't need to have that hardness to have that behavior.

    1095 properly hardened will put < ~0.6% carbon into solution which will ensure lathe martensite and is very tough even at a high...
