|New from Ronin Gear - Slot Handles! 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 simulated knife features a specially designed simulated 3.25 inch stainless steel blade which is perforated, rounded & dulled so it cannot be sharpened or turned into an active knife. Ideal for all types of knife training. Solid metal construction with belt clip; liner lock; thumb lug and 'spring assist lever'. 4.5 inches closed; 8 inch open. This enhances your training by making it more 'reality based'; something most plastic or wooden knives can't provide.

Note: this knife has a perforated, dull practice blade which cannot be sharpened! CAUTION: Always train under proper supervision. NOT designed for contact training!
