Indirect Percussion Sticks AKA Collins flexy stick

These Indirect sticks have evolved over the past year into what I believe is one of the easiest and most user-friendly indirect sticks on the market. 

They are available in four sizes. Size 1 being the smallest and great for the final thinning and cleanup flakes. And Size four being the largest and works great for reducing larger spalls fast. 

If I was to order just one, I would choose size three or if I was ordering a pair, I would order size one and three. With that said it is nice to have all four sizes for different situations.
