This oval 1 x 1-1/2" staff is about the same weight as the 1.25" round. Heavier than the more popular 1-1/8" quarterstaff.
So pick according to your strength.
This series of staves are made with 2 layers of impact grade hickory laminated together to form a strong, straight and defect free staff. This is the best wood possible for martial arts use. The hickory is strong, yet it is flexible to not be brittle when struck against other equipment. We hand oil at least 2 coat of a boiled linseed/mineral spirits mixture.
