I only have a few specialty tools for slot cars, but here are three very high quality tools no slot racer should be without.
Tire Razor...$120.00, plus $15.00 shipping. You all know how good this machine is. My Tire Razor is in excellent shape comes complete with belt, allen wrench, pulley wheel, and four sanding blocks, including the Tire Buddy. Round wheels and tires make a world of difference in how any car performs.
Hudy pinion puller...$20, shipping included. This is the gear puller that has set the standard for gear tools far decades. This is an heirloom tool. The blades that slip under the pinion are very thin making gears with little clearance easy to remove.
Hudy pinion press...$45, shopping included. Both of these tools are built to heirloom standards.
($55.00 for the pair with no shipping fees)
