This large well made Twosun TS81 is 8.82" open, 4.92" closed and blade is 3.78". Flipping action is very snappy with nearly no fail possible. The machined ribbing on the G-10 handles really work well for super secure grip with slippery wet hands. (see photos) Shipping is Priority USPS. Handling is same day or if after 3:30PM  PDT then next day except Sat. and Sunday.
