I have a set or Craftsman wrenches with both metric and English standard pieces. It came with a plastic pouch with a divider in the middle. I store the metric on one side the English standard on the other. Doesn't really work out all that well. I've mended the bag over the years, but realize this is not an efficient way to store these wrenches. They fall out; get mixed together occasionally, and it's difficult to sort them quickly.
Yes, I have a ratchet set, but for some reason I like using the old fashion wrenches from time to time.
I put the wrench bag in the tool box and go through the same trying process over and over again. Could use some suggestions as to how to better store these items.
Have a similar problem with screwdrivers, Phillips vs. straight. Need to get rid a lot of them. There is too much redundancy.
