I have this T/C branded vent pick. It appears to be intended for a flintlock since it comes with a pan brush attached as well. Take a close look if you can: It has grooves or jags along it. It would seem counter-productive to have grooves that would potentially collect powder and drag it back through the vent hole. What do you think? After reading about the pros and cons of blunt vs. pointed vent picks this one is kind of a monkey wrench. Is it going to do what it is supposed to or make things worse?
