A Tube o' schmoo?

[Ken from ontario]

I use Walter brand wax (Alucut metal cutting lubricant) bought it for lubricating drill bit tips for cutting deep holes in steel, it was amazing for that purpose but then I found out it work great on metal cutting blades, one stick will last a long time, years in my case.
I have also read good reviews on Olson saw lubricant:

Olson Saw Lubricant Stick

Olson makes a lubricant stick that works great to improve the cutting performance of manual and power saw blades.
