    When Did Humans Begin Hurling Spears?

    AFAIk the oldest spears have been found right here in Germany. They are over 300,000 years old, and belonged to a group of homo heidelbergensis hunters. This was a very early human, way earlier than the Neanderthal man. http://en.wikipedia.org/wiki/Sch%C3%B6ningen_Spears These spears...

    At last. A pumpgun slingshot tutorial.

    So many people wanted blueprints and tuts for my pump actions. But of course the Oreo one is useless, and the cardboard one is flimsy and weak. So I decided to make a really nice one that shoots M10 hexnuts. Those are very cheap (I buy 100 pcs for five Euros), last forever, and have the right...

    Traveling in the UK and Europe with a knife

    For Germany: small correction... folders that lock AND can be opened one handed can't be carried without a reason (self defense does not count). No length limit on folders that don't lock or can't be opened with one hand. Butterfly (Balisong) knives and out-the-front autos are actually...

    One of the best new products at SHOT

    I really appreciate that commercial companies are now looking into slingshots (again). However, the Beeman design leaves a lot to be desired. In fact, with minor changes, this could have been a far better shooter that still could be sold at the same price. First, arrow rest. It seems to me that...

    Chainsaws: Epic tips for crossbow bolts?

    hso, you are right, I need to calm down a bit. Sorry for that!

    Chainsaws: Epic tips for crossbow bolts?

    True, it will be ineffective and awkward. Expensive as well, as the "ammo" is not likely going to survive more than a couple of shots, best case. But still... come on, I will be launching a chain saw! Hahahahahahahaaaaaa...

    Chainsaws: Epic tips for crossbow bolts?

    OK, we all know that front heavy bolts need no fletching for a straight flight. What if... This January. On The Slingshot Channel. Stay tuned.

    9" nails as ammo: New slingshot pumpgun!

    The dimensions of the weapon depend very much on the size of the nails. A pattern would really only work if you use the exact same nails I have. It is not likely that this will be the case. The weapon is very easy to understand, though. Only two moving parts - the trigger/sear and the slide...

    9" nails as ammo: New slingshot pumpgun!

    Go right ahead an post it on facebook, that's fine with me. I used Thera Band Gold, 6cm x 13cm, two bands per side (looped). Since the video was shot, I added another identical band in Thera Band Blue, effectively making the bands 30% stronger. This is pretty much the limit of the material...

    9" nails as ammo: New slingshot pumpgun!

    Here is the video - sorry for the indoor filming, lots of rain. http://www.youtube.com/watch?v=95Xm-YT4FZ0 The weapon is very good for distances up to 15 ft - then the nails will start to tumble. If you use front heavy bolts (wooden, aluminum or carbon shaft, steel tip), then the...

    9" nails as ammo: New slingshot pumpgun!

    Here is my latest work... a repeating slingshot crossbow, shooting 9 inch nails. This is in continuance with my Chu-Ko-Nu based design line. This time, it is bigger than the pencil shooter, but a lot smaller than the chest mounted spear launcher. The ammo is - nine inch (23 cm)...

    James Bond's Slingshot Pistol

    Actually the OSS used rubber for these weapons... but I think these models have been very clumsy and next to impossible to hide. No field unit expressed any interest in them, so the research was abandoned. The few samples they made (prototypes) are now priceless collector's items.

    James Bond's Slingshot Pistol

    As the new James Bond movie has been released recently, I thought it is time to make a "007" slingshot. It has to be a pistol, and it has to be small of course. I settled for arrows as those can be poisoned and are therefore potentially lethal, even without great power. But if course it has...

    Twice as long - twice as good?

    Bands have to be longer (they stretch to about 5,5 times the original length), but the draw force is the same (same band width, just the length differs).

    Twice as long - twice as good?

    OK, I am talking about slingshot crossbows... nothing more, nothing less :) One of my most powerful slingshot crossbows is the winch operated hand cannon. It can handle much stronger rubber than any conventional slingshot. But it has an active draw length of only about 75 cm! The speed...

    Wary of carrying Cold Steel products?

    Prosecution and lawyers will always find a way to let you look very bad. Use a home made weapon and they will say that you are obsessed with arms, use a kitchen knife and they will say you used a butchering tool against a person and so forth. So you might as well carry what you like, and not...

    Watermelon Launch Woman: Why she failed

    Safety goggles are a MUST even if you shoot normal slingshots. A snapping band can easily ruin your eyesight. And every slingshot band will break - the question is when, not if. The girl in the video wasn't using any kind of protection. Whoever organized the contest was completely failing in...

    Watermelon Launch Woman: Why she failed

    The watermelon launcher accident is a very popular video, it clearly went viral. I get lots of related questions, and many fans don't want to use strong slingshots because they are afraid of such catastrophic misfirings. I have investigated and de-mystified the event. My conclusion: The...

    The Blunderbuss Slingshot

    After all these "special ammo" throwers (knives, spears, darts...), I wanted to make a more versatile weapon that is totally easy on the ammo. So I made a rubber powered blunderbuss! http://www.youtube.com/watch?v=fqWAM3Fd_vA This is so much fun.

    Homemade bullpup crossbow for under 20 bucks

    http://www.youtube.com/watch?v=Eu_kbfr_tdU Bullpups always fascinated me. There is something elegant and minimalistic about these weapons - plus, they are compact, but without any compromises regarding their performance. Made a new one this weekend, and I am quite happy with the result! I like...
