Every year we (are detailed to) perform a mass tool maintenance for each apparatus (above and beyond regular daily tool maintenance during rig checks and after jobs). The tools get stripped cleaned and re-painted as well as the compartments they are in. Then, right after they are inspected, the guys on the groups, go and strip all of the paint off of the tools, wire brush them and add new grip tape. Some guys apply light oil to the tools. I suppose it would depend on the frequency of fires in your area. If the tools do a lot of work you are not going to oil them regularly. Some guys are torn between paint on tools. By and large, most feel that the paint should be stripped off of the tools. We generally use a file on the axe blades to take burrs off. The grinding wheel compromises the temper. Lately guys have been putting grip tape (Hockey Tape) with a cable wrapped around the handle. My opinion is to keep at least one married pair clean on each apparatus, and square off the shoulders of the halligan.
