Flexible sledgehammer - GIF

[madokie]

i dont believe the speed did change,, when i swing a solid sledge hammer the handle and head is moving at the same speed as a flex handle,, if u watch the vid, the hammer head is flexed toward the back,,and it stays there till it hits target, it doesnt swing forward,,,,no more kinetic energy...to get more energy u would have to hold the handle and stop swinging,and let the head swing forward to hit target,(more speed),this vid doesnt show that ,,it shows a full normal type swing...which means to me that the flex head is always flexed to the rear,,not swinging forward..u tube vid Bendy Hammers,(flexible sledge hammer),, looks like made for when a lot of hammering is needed,to prevent handle breakage ..
