I have nails marked for all of my chains, then on a rainy day I start sharpening. My Stihl dealer has a chain special, buy one, get one free. I used to think he jacked the price up for the first one. Then I bought a 20" 3/8 for my MS290 at Southern States, the dealer was 3 dollars cheaper. So, now I wait till I need several chains and drive the extra 10 miles to the dealer. Then I started stacking the new chains, in their boxes, over the nails. But, I have the habit of putting the dull chains back in the boxes when I'm in my truck. Don't want to snag my new interior. Now every time I grab a box off the shelf, it's a dull one I forgot to take out and hang on the nail.
I‘ve been using these the last few years. I’m not usually cutting at home, and these help me keep them organized on the go. The one on the left is marked “dull”.
The pouches stay in the bucket, with the loose ones being chains that weren’t dull yet when I changed bar size.
Your post reminded me that I do have chains hanging in the garage, they’re getting pretty worn down though.
