HDSE stands for "Heavy Duty Special Edition" but it could also stand for "High Definition Special Edition." HDSE is identical in size and form to standard Rollerblock Jr. but has the following enhancements:
1) Top grade 7075 "aircraft" aluminum alloy body

7075 aluminum is harder than some steels and provides superior Brinnelling capacity (resistance to denting and deformation under extremely severe conditions) and superior mechanical coupling over 6061 aluminum.
