Never tried PB Blaster on knives but I'll testify that it's great on freeing up rusted, locked up machinery and bolts, etc. around the ranch. From my experience it's better for that purpose than either Liquid Wrench or WD-40.gwelker62 wrote:For the crusty rusty knives that are in need of a resurrection, don't think you find a better performing oil than PB Blaster penetrating oil.

Not intending this as a disagreement or argument, just to clarify. My testimonial regarding Tuf-glide comes from years of results. I am sure of how good a job it does. However after the carrier evaporates only the dry lube remains, which you can't see It like you can an oil product. But what can be easily seen is the results. I've seen Tuf-glide bring back the snap to a formerly lazy blade, free up rusted joints, and prevent rust on high carbon steel knives treated with it (even after being forgotten and left in the trunk of a car for several weeksLongBlade wrote:I have jumped around abit with lubricants (3:1, mineral oil and even tried Tuf-Glide - the latter I am not too fond of as I am not sure how good of a job it does) but have to say I do like Quick Release especially on old knives that need some loosening of blades that have sat for a long time.

I have used Quick Release, 3-in-1, RemOil, Hoppes, Ren-Wax, and White Lightning wax, graphite powder, and others I've forgotten over the years. They all have their pros and most are good products in their own ways, when used in the right application. I'll probably get tempted and try a few more - always looking for something better. I am an advocate of Quick Release - it's a great oil. But I do know oils attract dirt, and dirt will eventually attract moisture. In applications where dirt/dust is not a concern Quick Release is as good as it gets, best oil I have found for knives. I like it. If you're outdoors a lot and in a dusty environment, or just want a great protectant for your gear, IMHO Tuf-glide/Tuf-cloth is excellent. If I could just have one product only, it would be Tuf-glide.
Rant over! (It's cold, windy, and miserable here, so I'm resisting going back outdoors).
