Benchmade 51 Spacers
Couldn't load pickup availability
The spiritual cousin to Jimpy's discontinued Space Invaders, these Benchmade 51 spacers are made in-house from a rubbery, shatter-proof polyurethane. They extend and protect the handles of the BM 51, and enable adjustable balance with up to 2x removable tungsten weights per spacer. The adjustable weights allow you to adapt your BM 51 to suit your specific balance preference, no matter what scales or blade you are using.
Assembly Instructions: Tighten the body screws till there is a medium resistance and the handle liners are parallel. Do not overtighten the body screws— this can overcompress the spacer and narrow the channel. If you have calipers you can measure the width at the pivot and simply tighten/loosen the spacer screws till the channel width at the spacer matches the channel width at the pivots (~3.2mm). You can also use the stock spacer as a guide to the thickness by wedging it in the channel below the Zippy spacer and tightening the handles until they press upon the stock spacer; then remove the stock spacer from the channel.
-Extends handle length from 5.1 in to 5.6 in.
-Extensions protect your handles: These spacers are made from a shatter-proof polyurethane which will absorb the shock of drops, so your Benchmade doesn't have to.
-Adjustable balance: Each spacer houses up to 2x removable Tungsten weights which enables you to find the perfect balance to suit your preference. The weights can be popped out with a thin, rigid metal object using the slit at the base of the handle extensions, and can be popped in easily with just a pen.
-Adds jimping for extra grip on ladders.
-Each spacer weighs 0.090 oz empty, or up to 0.132 oz with 2x tungsten weights installed. For comparison, a stock Benchmade 51 spacer weighs 0.111 oz. With stock scales, Zippy spacers let the BM51 weigh 3.173 oz (empty) up to 3.258 oz (with all 4x weights).
Customer Reviews
If you are anything like me then you love Benchmade and Balisongs. More likely than not the 51 was your favorite flipper at one point, but as your collection grew your 51 just didnt have the weight or length you were looking for and was set aside to gather dust.
Well dust that bad boy off and get yourself a set these babies to give your 51 a whole new life. These spacers make it feel like a completely different knife and give you everything that was lacking from the stock 51. Plus they add some serious style points. 10/10 would recommend.
The 51 is short so the extra length was fantastic and the weight system is a godsent!
I've been in the hobby since the age of the Bradly Kimura full SS balisongs, the Benchmade 42, and of course the 51 Morpho. The first time I saw a modded 51 in a Knife Caviar video, I knew I had to have one. But alas it was not meant to be. Fast forward into the 2020s and I grabbed one of the last mint condition stock 51s I could find from an online retailer. I was stoked. I bought the Flytanium scales, the Zenith trainer, and of course some secondhand G10 Space Invaders. I got it all together and... it was handle heavy as all hell. Like, SUPER handle heavy. I was happy to finally fulfill my Grail 51 wish, but sad that the knife flipped so badly.
Enter the Zippy spacers. I can still have my long boi handle extensions with none of the extra weight. It's now an absolute joy to flip and I haven't put it down since the spacers arrived. These spacers made me love my 51 again.
I love the balance and overall feel of my heavily modded 51 with these spacers. very nice, cannot recommend enough
These spacers are lit! Definitely one of the top must do zippy mods if you have a BM51. The picture is with no weights.

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