Okay here is the deal. Lets look at this random picture of b12 in action (lmao):
First of all. Whole thing is steel for some reason. And this grip... Do you see that the character can't even wrap his arm around it completely? We could actually try to calculate weight of this thing. Let's assume that character hand is 2/3 of grip circumference. My palm (inb4 small hands) is 11 cm and 7-8 cm will be on fingers - 18-19 cm in total. So grip circumference is around 30 cm. Length of the handle is around idk 1,5 m? No idea how short heaven's characters are. But it will be close to meter and a half if we assume that they are around 180 cm. Back to calculations. Diameter of the handle is c(circumference)/pi ~ 9.5 cm. So r will be 4.75 cm. Next formula is volume - V = r^2 * pi * h. Okay google. 0.0128 cubic meter. Final step - lets calculate weight. Steel density is around 7850 kg/m3. Yes almost 8 tons per cubic meter. So our 0.0128 grip will have weight 100.48 kg.
Alright, it's not perfect cylinder and some numbers right from my ass. But I hope you'll get the point.
