Stielhandgranate M 24

I present my second independent work. A hand grenade with a wooden handle from the First and Second World Wars, the original name was "Stielhandgranate 24", but Soviet soldiers called it simply M-24 or "Kolotushka". I made three versions of this grenade: 
1. The simplest, basic option. 
2. A grenade, which is wearing a special fragmentation shirt, to increase the lethal force. 
3. The largest is the anti-tank version of the grenade. In fact, a murderous mixture of several grenades. 
Everything seems to have turned out well. 
I will be glad to welcome constructive criticism.
