  • These custom-made Zippy handle caps are designed and manufactured in house from a rubbery polyurethane and are virtually indestructible. They protect the handles from drops*** and add weight and balance adjustment with removable tungsten weights.

    Click here for balisong compatibility list.

    -A set of two handle caps weighs 0.13 oz empty, or 0.26 oz weighted with the included Tungsten.

    -Removable Tungsten weights to adjust the balance with just a ball-point pen or any rigid, thin, metal object.

    -Flexible and rubbery--protects handles by absorbing shock during drops.

    -Not brittle, won't shatter on drops.

    -Internal ridges to grip the jimping on your balisongs, so they don't slide off during drops.

    -Abrasion resistant and extremely durable.

    -If your goal is solely to protect the handles of your balisong, I recommend using these caps without weights or the Zippy Slim Caps: since the weight caps were originally designed primarily to work with Zippys, and the cap material is flexible and rubbery, there is always the risk that a tungsten weight contacts and "dings" the ends of your handles on a direct drop (this has not been tested with 3rd party balisongs). Slim caps do not house removable Tungsten weights, and therefore offer the best handle protection (alongside weight caps with all the weights removed).

    This product listing is a 2-pack (2 caps) or 6-pack (6 caps) of handle caps.

    ***These Zippy handle caps have been tested to fit on the following balisongs from other makers:  Click here for balisong compatibility list.

    Note that while the Zippy weight caps fit a variety of other balisongs, they were designed chiefly to work with Zippy's, and it's not yet clear how different handle shapes do/do not contact the tungsten weights during hard drops. Use with tungsten in at your own risk, as there is always the risk that tungsten hits the bottom of your handle on a drop, since the caps are a flexible rubbery material. I am not responsible for any damage your handles take during drops when used with 3rd party balisongs.

Works great

John honeycutt
Throw these on a squiddy trust me

Put these on a squiddy u for fun but was immediately surprised how much I like the added weight and grip for a usually slippery and lightweight flipper. Feels way more like an actually trainer and less like a toy

Well made and effective.

Got just the set of two, kinda confused myself and got 1 purple 1 gitd thinking they would be separate sets for some reason. Not a big deal, I'll end up buying another order of the same colors at some point to make them into pairs. Surprisingly high quality, especially for the price. I was skeptical of how well made something 3D printed could be, but I'm genuinly impressed. And the complete control over weight feels amazing when paired with blade inserts. All around amazing product for any balisong in need of more balance.

they work great!

Had a beater bali that was so neutral I couldn't flip it. No chaps and no fans. I ordered weight caps for another knife but decided to try them on the beater. its now my go to bali. Totally corrected every problem I had. slim caps are great for protection. A set of glows are currently on my machinewise and its saved it from getting ate by concrete many times. I highly recommend flippers to get these. low cost and high function.

These are made very well. They are indeed extremely durable and function exactly as the site explains. The modular tungsten ball weight system is really cool. Nice color selection too the transparent pink is amazing. I put them on and then took them off again after 24 hours when I realized that I actually prefer neutral flippers. When I bought them I sincerely thought that I wanted to add weight to the handles. But I no longer like handle bias on my balis. Also they aren’t as comfortable as I has hoped. They are not smooth at the butt end. there is a kind of scratchy seam that is there from the plastic molding. process. I can feel these seam lines going around the edges. This isn’t as comfortable as i was hoping for I can feel it when doing palm fans and choker fans. I’m not using these at the moment but I appreciate owning them in case I can trade or gift them to someone some day. I’m also seriously considering buying the unweighted handle caps because those look good too

Product Information


International shipping

International Shipping

Zippy ships international, but the buyer accepts the risk for lost, damaged, or seized packages-it is the customer's responsibility to comply with all local laws and regulations when importing and using this product. It is the customer's responsibilities to be aware of all import requirements when ordering, including but not limited to paying customs/import/duty fees. All international customers: it is your responsibility to looking up your country's customs requirements when you order to ensure you are in compliance, and interface with your country's customs and pay all associated fees if necessary.

For EU customers, be advised that customs will apply a VAT fee of approximately 30€ for importing products that exceed 100€. This is subject to change depending on up-to-date EU regulations; it is the customer's responsibility to verify this at the time of your purchase.

For questions and concerns (looking at you, Aussies), please contact me at If the Zippy is shipped in 2 packages, you will need to assemble the trainer following these instructions:

Cycloid Assembly

My package hasn't arrived, or my package is lost; what should I do?

Noooooo! Don't panic yet. So far I've never actually had a package get lost in the mail, although delays with USPS aren't unheard of, especially if the shipping is international. If you're a US-customer and your package is lost in the mail, appears lost in the mail, or was marked delivered but wasn't actually delivered, call the USPS immediately (1-800-275-8777)**. The faster they get on the case, the more likely you'll reach a timely resolution and get your Zippy ASAP. You can email me about it, but once I ship it out, I don't have access to any additional information that you don't--I'm just going to refer you to call the shipping carrier for resolution.

**Some tips when calling USPS:
(1) Do not use speakerphone, as this will confuse the automated system.
(2) From the automated menu, say "Package," and follow the prompts with your tracking number.
(3) When it offers "visual mode," I recommend you use it. It's faster and more streamlined.
(4) At the end of the automated system which will track your (delayed) package, say "agent" or "representative" so you can speak to an agent and explain the issue.
(5) Sometimes they only allow the sender to open an investigation. If that's the case, shoot me an email asking for the shipping label, and then use the return address information on the shipping label to provide the sender information.

If you are an international customer and your package hasn't arrived yet, contact your local postal service that interfaces with USPS to evaluate the situation--worst case scenario you may need to reach out to customs to see if your package made it through or was seized. It is the customer's responsibility to comply with all local laws and regulations when importing my products.

Hopefully your package is just delayed (this has always been the case historically when a package appears lost), but if it is actually lost in the mail, I'm very sorry. Believe it or not, it's just as heartbreaking for me as it is for you, since I make every balisong myself and put a lot of love into each one. Unfortunately, I am unable to take responsibility for packages that get lost in the mail (or seized by customs). I offer a variety of shipping options which have different levels of pricing and reliability/risk, and it's up to you to choose what is best for you. I am unable to replace lost packages for free, since each product takes me a considerable amount of time and financial investment to make; I'm not a big Amazon company that manufactures their stuff overseas. Thank you for understanding.

Warranty & Returns


If part of the Zippy breaks within 1 year of purchase and it affects functionality, I will replace it for free. Contact me at

In order to qualify for this policy, the issue must affect the function of the balisong. Normal wear and tear (including scratches and dings caused by repeated impact) is not covered by this warranty unless it affects the functionality of the balisong or I determine it to be the result of a manufacturing defect. In order to reduce cost for the customer, the Diode is not covered under the Zippy Warranty. Replacement Diode parts can be purchased here.

Worn M2 x 0.4mm nylock nuts are consumables and should be replaced from time to time if you disassemble frequently--these are not covered by the warranty.

Returns & Order Cancellation

I do not accept returns or refunds. All orders are final. Packages that are delayed or lost in the mail are not my responsibility. Many of my products are made-to-order and by the time you contact me to cancel, I may have already begun working on your parts. I am a one-man operation and returns are far too time consuming and costly to deal with. I appreciate you supporting my small business.
