Cool new slip joint design from Tsunoda.
Jaws are a bit narrower vs the old design but, also feel much lighter.
New pliers have three slot design similar to Snap-On and Knipex models which allows then to grip larger bolts and etc.
New design has recessed pivot point making them even narrower.
New design only comes in bare metal handles. Personally I've always preferred the traditional plastic dipped handle, never tried bare metal.
The most interesting design and only original/new aspect though is the curved jaws. They're meant to grip in the middle of bolts so you didn't round the corners and help gripping angles in general. Never seen that before, will be interesting to see how it works out in real world use.
