Layaway Information

Layaway Policies

We offer a layaway plan on select products so you may pay for your order over a period of 60 days. Products that are eligible for layaway will show "Layaway Available: Yes" on the product page.

Here's how it works:

The total amount of the order excluding shipping, tax, or fees is divided into three (3) equal payments. The first payment is due with the order, the second payment is due 30 days later, and the final payment is due 60 days after the order.

There is a $15 non-refundable fee for layaway orders. This fee is added to the first payment along with the shipping and any tax. The first payment is made when the order is placed.

Example: Your order total is $300 plus $12.75 shipping and handling. If you select the layaway option, your payments would be:

  • $127.75 (1/3 of purchase = $100 + $15 layaway fee + $12.75 shipping)
  • $100.00 (1/3 of purchase = $100)
  • $100.00 (1/3 of purchase = $100)

If your initial payment is made by credit card, we will automatically process the 2nd and 3rd payments at the appropriate time using the same credit card information. You will be reminded via email that a payment will be charged. If you need to change this for any reason, please contact us.

For payments made other than credit card, payment must be received within seven (7) days of the due date or the order is subject to cancellation. You will receive a reminder via email that a payment is due.

If you wish to complete payment early and have your order shipped, you may contact us at any time during the 60 day period. There is no penalty for prepayment.

Additional products may be added to a layaway order without penalty. A new payment schedule will be calculated based on when additional products are added.

If you wish to complete payment early and have your order shipped, you may contact us at any time during the 60 day period. There is no penalty for early payment.

Cancellations of layaway orders are subject to a restocking/processing fee of 10% of the order total (not including tax and shipping costs). This restocking fee is in addition to the $15 non-refundable layaway fee.

Overview

This Serum dual action folder from Benchmade features a black blade and milled black G-10 scales, stainless steel liners and tip up clip that can be positioned for right or left hand carry. Includes original packaging and paperwork. Excellent condition. 

The 5400 Serum knife features the revolutionary AXIS dual-action mechanism. One of the strongest, most versatile automatic mechanisms on the market for nearly 20 years has evolved. The AXIS Dual-Action automatic or manual opening combines the superior ambidextrous function of the manual AXIS with a covert automatic action triggered by pulling the AXIS bar down further. No matter the job, the AXIS dual-action has you covered.

Featuring 154CM stainless steel, this is a proven steel for tactical applications. Its well-balanced characteristics promote performance in the most demanding situations asked of in a tactical folder. 154CM is a martensitic stainless steel with molybdenum content. The molybdenum is what gives 154CM good toughness which is based off a combination of ductility and strength. In addition, 154CM has good hardness and corrosion resistance qualities.

Operating the 5400 Serum:

The Benchmade 5400 Serum™ features the AXIS Dual-Action mechanism which can function either as a AXIS manual or as an AXIS auto. To operate the knife as an automatic, pull the AXIS bar back to the furthest position to actuate the automatic opening function.

The AXIX Dual-Action mechanism has a "dry-fire" safety that initiates when the blade is not fully closed. This features aids in the safe operation of the knife and prevents the automatic function from firing when not intended to be used.

About the "Dry-fire" Safety:

The AXIS Dual-Action mechanism has a secondary safety system built in to eliminate a "dry-fire." A dry-fire is when a torsion or leaf kicker spring is released without adequate resistance. The uncontrolled release of energy is unstable and can cause the spring to fracture. In addition the potential of a catastrophic failure, a dry-fire can greatly reduce the life of the spring and create a dangerous situation for the user with the spring unwinding and colliding into the blade. This situation would result in the knife opening in an unpredictable manner.

The dry-fire mechanism locks the automatic mode out by blocking the lock stud from going back far enough to release the spring bushing.

The dry-fire safety is engaged whenever the blade is not in the closed position. The AXIS® lock bar provides the closed position detent. Pulling back the AXIS bar will release the detent and can allow the blade to open partially if the knife is held horizontally. In this case the dry-fire safety will engage. To actuate auto mode, the blade must remain in the handle until the bushing is released and the spring uncoils.
