    Product Description

    Adjust the balance of your Glidr Bermuda trainer with the Zippy blade insert and spacers. The spacers remove end-weight, while the insert adds tip-weight. Together, these mods provide a far more neutral balance profile for the Glidr Bermuda.


    • More neutral balance: Blade inserts add up to 6x removable tungsten weights to the blade to reduce the handle bias. The weights can be popped out with the tip of a ballpoint pen and can be popped in with your thumb or any rigid flat object.
    • Spacers shave off 0.11 oz from the ends of the handles for reduced handle bias.
    • A pair of Zippy spacers weigh 0.050 oz. For comparison, a pair of stock spacers weigh 0.160 oz
    • Spacers feature positive jimping for extra grip on ladders.
    • Insert fits securely and won't fall off on hard drops.
    • Made of shatter-proof polyurethane.
    • The Zippy Insert Mod adds 0.043 oz without weights, and 0.171 oz with all 6x weights.
    • Add-on optional Zippy Slim Caps for only $5 (30% Discount) to protect the handles of the Bermuda.

    Assembly Instructions

     If you have trouble inserting the mod, try to pop it in without the weights, and then equip the weights when the mod is already installed in the Bermuda. To install the spacers, simply unscrew the T8 screw at the bottom of each handle, pop out the old spacer and black metal pin, pop in the Zippy spacer, and retighten the screw. If you are having difficulty unscrewing the spacer, alternating time in the freezer and in boiling water can induce thermal contraction/expansion that loosens the factory overtightening. My Bermuda required approx. 2 hours in the freezer, followed by 2 minutes in boiling water, after which I immediately attempted to unscrew the T8 screw at the base of the handle.

"It actually IS black magic but I try not to spread that around" - Zippy
So I already had a Bermuda insert in the trade, and while it was much better than stock, it was still a bit too handle biased for my tastes. Once I ordered a pair of spacers however, it's somehow gone from something I was about to sell to something that I might just keep permanently. Trading out the g10 spacers for Zippy's spacers made a massive difference. It's somewhere between neutral and lightly handle biased. The Bermuda is still heavy, as is it's nature, but having the more neutral and distributed balance with the bearings makes it feel surprisingly nice. The positive jimping from the spacers is great as always, and chaplains are as sticky as ever(just like me fr) while fans and other tricks feel nicer than before. I also like the look of the pop of color at the ends of the handles, I got translucent forest green and translucent purple, my favorites from Zippy's collection. Everything was easy to install, and the insert won't fall out if inserted correctly.
Zippy, the goat as usual, surprising nobody.

The spacers are so good!

Everyone talks about the blade insert which yes is good. But for me the spacers are where it's at. The spacer cuts a lot of the butt weight out of Bermuda. Over a 10th of an ounce on the ends makes a surprising amount of difference. I have my Bermuda with the spacers and an inlay with no weights and it's like the stock bermuda but less handle bias. I've flipped one with stock weights and all weights in the blade and it's the stock bermuda but heavier and less handle bias.
Now to no fault of Zippy BE WARNED that the hardware is BAD and it's very difficult to remove without stripping. I had to drill some of the screws out and didn't even 100% succeed. But if you can remove your hardware without stripping the spacers are EXCELLENT

Will later link my youtube video review

you need these

for real tho you gotta get these for your bermuda. I love the blacked out blade look of the blade insert and the additional weight feels nicer with fans. color options popping, I love being able to customize something to this degree.

Definitely worth it!

This makes the Bermuda a lot more fun to flip for me! I love the spacers and the blade insert adds so many difference balance options:)

The Bermuda Balance Mod is worth every penny!

The blade insert is a major help balancing out the Bermuda to make it much less handle heavy(about the same handle bias as my triton). The spacers also make a difference, although slight, alleviating the handle heavy balance of the stock Bermuda. Overall, I would buy these mods no matter what since they do make the balance of the Bermuda significantly more enjoyable and flippable for the large majority of flippers.


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:

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.

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.
