Blitz Sport Standard Rubber Knife Training Weapon Review

When training in martial arts, especially self-defence, there are times when you need to learn how to defend yourself against knife attacks. Of course, the first rule is to run away from any attacker who is armed and dangerous, but sometimes escaping isn’t an option if the attacker is in close proximity or pins you against a wall.

In martial arts such as Japanese Ju-Jitsu, Krav Maga and Kali, knives are used during training and the key to good defense training is making sure the training weapon is fit for purpose.


The Blitz Sport Standard Rubber Knife is a good-quality training knife that is ideal for use in the dojo due to it’s flexible construction.

Weighing in at 125 grams, it’s a similar weight to that of a real knife and measures 9.5 inches in length, 5.5 inches of that being the silver blade.

The shape of the Blitz Sport Rubber Knife is very realistic and even comes to a point at the end and on the blade itself, though it is not sharp to injure yourself or your  training partners.

The firm black handle has an embossed criss-cross pattern to retain grip on the knife at all times, which is really useful when your hands get sweaty during a long training session.


When I’m training in Japanese Ju-Jitsu, we quite often use takedowns which result in the ‘attacker’ loosing the weapon half-way through the technique. This can result in martial arts students falling on the training weapon which could be very uncomfortable indeed! I’m pleased to say that the Blitz Sport Rubber Knife passed the test, causing no injury when fallen on.

Though it is a rubber weapon, the Blitz  Rubber Knife is not flimsy at all and is quite sturdy but will bend when in contact with a solid object such as a human body.

The training knife feels comfortable to use when attacking with various techniques such as overhead plunging, diagonal swipes and straight stabbing motions, and equally useful to use when defending. It’s very hard to visualise a weapon attack without actually having one to defend from but this rubber knife is the safest and most practical solution to this issue. Having a defined blade also enables you to work out which techniques work and which don’t. The last thing you want to do is slice yourself up when defending. One of my favourite disarming moves when facing an attacker with a knife is a sidestep and wrist lock.  Of course, it always depends on the attack but wrist locks are generally the way to go.


I’m very impressed with this rubber knife, the quality is substantial and it serves its purpose very well as a safe training substitute for a real knife. I’ve used quite a few rubber knives in the past at various clubs but I must say the quality of this one from Blitz Sport is impressive, especially for the price of £5.99. I would definitely recommend this item to anyone who practices, or wishes to learn, attacks with and defence techniques against knives.

The Standard Rubber Knife is available for £5.99 from Blitz Sport
