Facom Dead-Blow Monobloc Hammer - 3 lbs (216.60) - these are my favorites among Facom's various "dead blow" hammers. Excellent quality. The head of the hammer is filled with steel shot, the mass of which has sufficient inertia to counteract any rebound. The monobloc design protects the head from splitting and releasing the steel balls. D45 +/-5 shore hardness impact surface. Comfortable PVC grip.

Note-this is the hammer I used for setting concrete paver stones....large 60mm contact surface and 3+ lbs of mass help set the pavers with minimal risk of damage.
