    Hi everyone!

    I'm not sure if this has been answered on the forum (I'm sure it has and I'm too lazy to look haha!) - I just finished three-hours worth of annoying saya-making only to find out that the wood glue that I used (Titebond III) may cause steel to rust even after it's been dried and cured? Here and here.

    But apparently, wood glue has low pH, i.e. high acidity?? For those who have made their own says with wood glue (Titebond, Elmers, etc.), have you encountered any rusting on your knives? Any input would be greatly appreciated! Thanks!

    I have not, but my sayas are only used for travel storage. I always considered the wood from sayas to hold enough moisture to concern me. I have advised my saya clients not to use them for long term storage without vci paper.

    I haven’t experienced this with titebond. I have, however, seen certain kinds of wood cause severe reactions when in contact with carbon steel. Purpleheart in particular caused crazy rusting. Will never use that again...

    I’ll agree that the primary use of a saya is for protection in transport. Not really recommended for long term storage, particularly for carbon or even semi-stainless.

    Got it. Good to know! I've been keeping my knife in vci paper, but good to know that sayas primarily shouldn't be used for more than transportation purposes.

    Thanks everyone!

    FYI, Vci paper has an expiration date. Generally it is two years.

    i dont see how that saya/glue combo would rust the blade more or less than any other wood. drill a hole at the bottom so you can let air out if the says is ultra tight.

    only thing i heard about wood rusting steel is oak and it was probably just BS.

    just oil the blade, done.
