What if my reed knife gets rusty?
All reed knives are made from tempered hardened steel, unlike most kitchen knives. While a steak knife or pocket knife blade, traditionally made of stainless steel, will not be affected by rust to any large degree, it is almost impossible to sharpen such a knife in any meaningful way.
All the knives we carry are specifically made to be resharpened by the reed maker about every ten minutes or so, as the process of reed making wears down the ultra-fine burr on the leading edge of the blade.
While this is all well and good, it also presents a problem: this kind of steel is prone to rust.
We ship knives with a thin coating of oil on them, and they are traditionally sharpened on an oil stone, which gives them access to a constant oil source, making them fairly resistant to rusting. In addition, the sheath of these knives becomes quickly permeated by the honing oil, allowing the knife to have a nice, safe rust preventative home.
When a knife has been regularly stored with moisture on the blade, or if the sheath has been permeated by water, the chances that rust will appear are heightened. This is a consistent message in double reed making books, and most teachers will apprise the student of this, if it was not an automatic assumption.
However, young players have been known to not put their tools away completely clean, or at all. People are not born knowing these details, but there is a basic assumption that the owner of a tool will provide minimal care. In this case, that means wiping the knife off before putting it away.
In any case, here are some helpful hints on how to remove the rust:
1) Immerse the blade in lemon oil overnight, and wipe dry the next day. If this did not work...
2) Rub the metal with steel wool and WD-40 and then leave a thin coat of WD-40 on the blade for a few days. Examine the sheath and if it is wet - dry it and then spray a thin coat of WD-40 in it. Try rubbing the blade again with the steel wool, if all the rust has not already been taken off. In most cases, all the rust will not be able to be removed, or there may be a coloration left behind on the face of the blade. Neither of these will render the knife unusable, but keeping the knife dry will aid in not having this reoccur.
