That is 100% correct. I have done extensive research into this topic and have come to this exact conclusion. It is quite humid where I live now and the use of a dehumidifier is required. I maintain a constant humidity and temperature. It is fluctuation in humidity and temp. that cause damage, especially in composition items. I use 50% humidity because I have rifles also. Also, as Houston indicated, store your daggers outside of the scabbards and give a periodic inspection. If you see oxidation beginning to form on the metal surfaces, it's probably too late.. I use a thin film of high quality gun oil on my blades and inspect daily. I also leave a ceiling fan on to keep the air circulating.....

The problem with the gene pool is that there is no lifeguard.
