## Description

New from Ronin Gear!  Slot Handle Spring Assist  #B

Designed to make your training more effective by adding the psychological aspect of handling an assault with a realistic folding blade!  This heavy-duty spring assist knife features a drilled 3.25" stainless steel rounded & dulled blade which opens with a touch of the lever.  Ideal for all types of knife training.  Solid metal construction with belt clip, liner lock, thumb lug and 'spring assist lever'.  4.5" closed, 8" open.  This enhances your training by making it more 'reality based'; something most plastic or wooden knives can't provide.

There are no sharp edges to cause serious injury. 

Note: this knife has a dull practice blade which cannot be sharpened.
