Trying to re-org the tool system (again), and slowly converting to systainers. I have a small trim stool that holds lots of indispensable tools during trim out, especially hardware install. I can sit on it to mortise strike plates and such and stand on it for a million reasons. Had it for 20 yrs at least and really wish there was a festool replacement that integrated with the T-locks. Imagine being able to stand on systainer?, you could adjust the height by stacking, hell you could make steps if you really wanted to.
