Those look like they work well. No way I could ever do something like that. My wife smokes, will not go outside to do it and sure as hell will not quit. In trade I get to buy pretty much what ever I choose as far as militaria. She even gets me a bayonet every once in a while.
I am currently in the process of putting together an air tight, moisture proof, acid free inner environment display for a WWI German Ks 98 with it`s original frog, a trench knife, belt buckle and a few medals. If I ever quit getting distracted and finish it, I will post it on the forum.
As far as my S84/98 III bayonets and other Ks98 s, they get put in an old clean sock and then put in an air tight container with desiccant packets between layers. I take them out every three months,(or when I just want to look at one of them) to make sure all is well. It rains a lot here at times and rust can pop up fast.
