Are there any knives with differential steels to make the knife? The idea is similar to differential heat treatment to make the cutting edge of the blade hard, and the spine and other portions tougher. I know that there are examples of knives where steels are folded, where the harder steel is on the outside and the softer/tougher steel is sandwiched on the inside. Or, where various steels are folded and layered to make the blade.
But, what about harder steel on the cutting edge portion (e.g. M390 with HRC 62), which transitions to the spine/handle area to a tougher steel (e.g. steels used for axes; or a different hard steel made tougher with heat treatment, or even a titanium alloy)? It may not have much of an advantage over differentially heat treated, single steel blades; but I think it would look interesting if you have, say, a modern super steel like M390 which then transitions to Wootz (e.g. where brut de forge would typically be at).
Not sure how the bi-metal border area would fuse the two steels together, so maybe folding is necessary, but you would still have two different steels separated into distinct regions of the knife.
Do they exist? Difficult? Impossible? Thanks in advance.
