Product Description
The Amalgam C234CFP is a practical working knife that combines Spyderco's Compression Lock, a fully accessible Trademark Round Hole, and a flipper opener in one package. Spyderco credits the design to Brian Lai, who created it as a college student. It pairs a broad CPM S30V drop point blade with textured carbon fiber/G-10 laminate scales.
CPM S30V is an American particle metallurgy stainless steel designed specifically for knife blades, with a balance of edge retention, toughness, and corrosion resistance. The 3.8" blade is full-flat ground on 0.138" stock for clean slicing, and its broad drop point profile handles everything from breaking down boxes to food prep. The blade rides on low-friction ball-bearing washers for smooth opening with either the flipper or the Round Hole.
- Blade: 3.8" CPM S30V drop point with a 3.4" PlainEdge, full-flat grind, satin finish, 0.138" thick.
- Handle: Textured carbon fiber/G-10 laminate scales over nested, skeletonized stainless steel liners; 5.1" closed, 4.3 oz.
- Deployment + Lock: Flipper tab or Spyderco Trademark Round Hole, on ball-bearing washers; the Compression Lock releases from the spine side, so your fingers stay clear of the closing blade.
- Carry: Four-position pocket clip for tip-up or tip-down carry on the right or left side, plus a lined lanyard hole; 8.9" overall.
Ideal for: users who want a full-size working folder with a broad slicing blade; flipper fans who still want the option of a Round Hole; and anyone who wants smooth action on ball-bearing washers in a Spyderco.
The Spyderco Amalgam in CPM S30V with carbon fiber/G-10 laminate (C234CFP) ships same or next business day from Columbia, Louisiana. Knifeworks is an authorized Spyderco dealer.
Spyderco Amalgam: Frequently Asked Questions
Answers to the most common questions about the Spyderco Amalgam (C234CFP).
What lock does the Spyderco Amalgam C234CFP use?＋
The Amalgam uses Spyderco's Compression Lock, built into the nested, skeletonized stainless steel liners. When the knife is open, a leaf spring in the liner wedges between the blade tang and the stop pin. You release it from the spine side of the handle with one hand, which keeps your fingers out of the blade's path as it closes.
How do you open the Amalgam?＋
The Amalgam gives you two ways to open it with one hand. You can pull back on the flipper tab with your index finger, or use the Spyderco Trademark Round Hole with your thumb. The blade rides on low-friction ball-bearing washers, so both methods open it smoothly with either hand.
Who designed the Amalgam?＋
Spyderco credits the Amalgam to Brian Lai, who designed it as a college student. His goal was to combine the advantages of the Compression Lock, the Trademark Round Hole, and a flipper opener in one practical, versatile working knife.
What is the Amalgam blade good for?＋
The C234CFP has a broad 3.8-inch CPM S30V drop point blade with a 3.4-inch PlainEdge and a full-flat grind, so it slices cleanly through boxes, rope, strapping, and food. CPM S30V balances edge retention, toughness, and corrosion resistance, and it sharpens well on diamond or ceramic abrasives.
What comes with the Amalgam C234CFP?＋
The C234CFP ships as a knife with its four-position pocket clip installed. It is knife only, with no sheath or lanyard included. Packaging and included items are set by Spyderco and are subject to change.
