The bow is short, just 80 cm (31") and entirely made from plywood (minus the scales). The bow "limbs" are rigid, as the string is made from pretensed rubber (what else). The weapon is solid enough to handle spear gun rubber, which clocks at 120 lb draw force - well in the English warbow class.
I even made my own arrows, from 10mm (.40") dowels. My longest arrows are 35", very heavy with medieval style broadheads.
I am not an experienced archer, but it performs well.
