  1. I haven't taken any sides either. I have three sets of screwdrivers and one set has parallel blades. I was simply reacting to other statements that seem to think that parallel blades are gospel and that tapered blades are wrong.
  2. If the slot is only a fraction wider, the two points of contact will be on the opposite corners of the blade on the diagonal of the slot. This causes tensile stress which can cause more damage than a traditional v-shaped blade in the correct size because it evenly grips the full length of the slot.
  3. As with so many things, there's no good or wrong. This has been debated for decades and it won't be settled with 1 picture. The best thing is to have multiple sets of screwdrivers so you can use the best one for the job. The picture makes sense but only because the one on the left is a perfect fit. If the slot in the screw is only a fraction wider, it doesn't work. So, you'd need a different screwdriver.
  4. Careful, guys! Not many things make watchmakers lash out more than screwdriver blade shapes and which oils and greases to use where
  5. I also find it odd to immediately have everyone's screwdrivers hollowed. A friend of mine is also an Omega certified watchmaker but has never used a parallel blade in his life. The same goes for Anthony from NoBSwatchmaker, who's certified for Rolex, Breitling, JLC, and Omega. No doubt that parallel blades are useful in some cases but it sounds like a personal thing from the teacher. *edit The great George Daniels was also all about flat ground screwdrivers.
  6. I agree. From what I know, The British Horological Institute and watchmaker schools in the Netherlands teach to work on watches with flat ground screwdrivers. Hollow ground is useful for screws made of a softer metal such as gold and convex screws that you sometimes see in older watches and also sometimes used as case screws.
  7. I think it's either a collet closing tool or a tube tightener.
  8. Nice watch! The case doesn't look so bad to me.
  9. I just sold the K&D staking set so it's not available anymore. Sorry
  10. Sorry about mentioning prices. I only wanted to help a fellow member and be as clear as possible. I won't do it again
