got a couple of nice leather sheaths made for my busse blades (not stainless, better, imho) by chuddybear. i asked him how to store my knives (okay to store in sheaths). he said just to put light coat of oil, and it was okay to store inside the sheaths. he also said to check on them every month or so and maintain them. if used, clean blade and sheath, let both dry out completely, apply oil and back in to storage. been doing it for 4 months now and no problems. be sure to keep a dehumidifier with knives (silica gel packs). recharge dehumidifier as neccesary. i live and play in hawaii (humid, sometimes wet, and surrounded by salt water [pacific ocean]) and this seems to work for me! also use same procedure for my crk's, kiku's, hattori's, kanetsune's, emerson's, ranger's (both ss and high carbon steels).
