    Has anyone ever tried using a small strong magnet on end of saya pin & a small piece of magnetic steel built into the saya rather than a friction fit for holding saya pins in place?

    Any reason NOT to try doing so, asside from tradition?

    I considered this, but magnets attract and hold any magnetic "trash" in the environment- Possibly leading to scratches on the blade when moved in and out against such trash.. I DID build magnets into a home made "saya" for my brush knife, which doesn't care about blemishes on blade finish.

    I accidentally magnetised an iron clad white #2 usuba. Blooming nightmare to sharpen as all the swarf sticks to it.

    I am really sceptical of anything magnetic near any of my knives.

    What would be cool is a saya that you can lock.... stop colleagues, kids or SOH using your baby. Something with a retina scan or some such:rolleyes:

    A magnetized knife would be a horror to sharpen- Do you have access to a magnetizer/demagnetizer?

    My idea for designing this would not place the knife blade in contact with a magnet, in use, the blade would be a cm or so ahead of the small magnet- Magnet would be recessed into the wood slightly to prevent contact with blade during insertion and removal from saya.

    As far as a locking saya? That's a GREAT idea. Not a keyed lock, but a "puzzle box" approach where you have to know a progression of moves to open the thing: see 9:40 into this video for a simple version of a puzzle box lock.
