After watching countless hours of woodturning videos on Youtube, it seems like a 5/8" bowl gouge is very common. I started with a 3/8" from PSI, and decided that it was too small, so I decided to pick up a 5/8". I went to Rockler to buy one, and couldn't find a 5/8" bowl gouge anywhere. I ended up buying a Carter & Sons 5/8" on Amazon, and couldn't be happier with my purchase.

Is it weird that Rockler didn't carry this size? I know Youtube doesn't always reflect reality, but I was quite surprised not to find this item on hand.
