What is the Difference Between a Slapjack and Blackjack

slapjack and blackjack

The slapjack and blackjack melee self defense weapons fall under the classification of clubs because they are used as blunt weapons. The two may look very feeble due to their sizes, which are at times no longer than the forearm (including the handle).

Despite their sizes, these have the capability to cause serious injury, knockout or even kill someone if used at their full force and effectiveness. There have been many reports of deaths stemming from a slapjack or blackjack shot to the head, so a lot of places have banned these self defense tools and have classified them as deadly weapons.

But what is the difference between slapjack and blackjack? This was a question recently sent to us via Best Self Defense Weapons Mailbag. Here’s a quick look at their features:


The slapjack, also known as the flapjack, is an elongated leather-covered weapon. Inside it is a piece of flat metal which is composed of lead. The flexible metal usually runs from the handle all the way to its opposite end making it pretty solid. Sometimes, a ball of lead is also placed on its tip to make it more damaging.

Basically, it creates a slapping sound when it gets into contact with the skin of the target due to its flat leather surface that’s why it is called by its name.


The blackjack is the nasty cousin of the slapjack. It is usually made with the same set of materials used in the slapjack, but sometimes, the leather is substituted with nylon or durable synthetic fabric.

Unlike the slapjack, it is shaped like a little club or a miniature baseball bat. The top and base of the blackjack are round and the product is denser than the slapjack too due to its heavier metal content.

Which is the More Effective Self Defense Weapon Between Slapjack and Blackjack

The blackjack is much deadlier because it has the capacity to break or even shatter bones when used with maximum force. More deaths occur from a blackjack shot than a slapjack’s, but never discount the fact that the latter can be a formidable weapon as well in the hands of an experienced or trained fighter.
