Product Description
⚠️ Automatic knife legal notice: This is an automatic (switchblade) knife. Automatic knives are restricted or prohibited in many states and municipalities, and the federal Switchblade Act restricts their interstate shipment. It is the buyer's sole responsibility to verify and comply with all federal, state, and local laws before purchasing. For current state-by-state information, visit akti.org. Orders to jurisdictions where automatic knives are restricted cannot be fulfilled.
The Avispa, Spanish for "wasp," is a Jeff Randall and Mike Perrin design from ESEE, offered here as an automatic under the BRK name. This version pairs a 3.5" stonewashed 14C28N stainless drop-point blade with black G-10 handle scales and a crossbar lock, with a thumb slide for opening.
14C28N stainless steel is a fine-grained stainless known for taking a keen edge, sharpening easily, and resisting corrosion, which makes it a practical choice for everyday cutting. The flat-ground plain edge slices cleanly, the stonewash finish helps hide scratches from daily use, and the black G-10 scales are durable and grippy.
- Blade: 3.5" 14C28N stainless steel drop point, stonewash finish, flat grind, plain edge, 0.13" thick.
- Handle: Black G-10, 0.55" thick.
- Deployment + Lock: Automatic opening via thumb slide; crossbar lock.
- Carry: 5.40 oz, 5.0" closed, 8.5" open, with a tip-up, right-hand carry pocket clip.
Ideal for: collectors of ESEE designs who want the Avispa in an automatic version; everyday carriers in jurisdictions where automatic knives are legal; and buyers who want a stainless blade with a secure crossbar lock.

BRK Avispa Auto: Frequently Asked Questions
Answers to the most common questions about the BRK Avispa Auto with a stonewashed 14C28N blade, black G-10 handle, and crossbar lock (BRK1304).
Is the Avispa Auto legal where I live?+
It depends on where you live. Automatic (switchblade) knives are restricted or prohibited in many states and municipalities, and the federal Switchblade Act restricts their interstate shipment. It is the buyer's sole responsibility to verify and comply with all federal, state, and local laws before purchasing. For current state-by-state information, visit akti.org. Orders to jurisdictions where automatic knives are restricted cannot be fulfilled.
What kind of lock does the Avispa Auto use?+
It uses a crossbar lock. A spring-loaded bar moves across the handle behind the blade to hold it securely open. To close the knife, retract the crossbar and fold the blade closed, keeping your fingers clear of the blade's path.
What kind of blade does the Avispa Auto have?+
It has a 3.5-inch 14C28N stainless steel drop-point blade, 0.13 inch thick, with a stonewash finish, a flat grind, and a plain edge. It opens automatically using the thumb slide.
What is included, and how does the clip carry?+
The knife comes with its pocket clip installed for tip-up, right-hand carry. No sheath is included. Contents are subject to change by the manufacturer.
How do I care for the 14C28N blade?+
14C28N is a stainless steel that resists corrosion but is not rustproof. Wipe the blade clean and dry after use, and keep the action free of lint and debris so the automatic mechanism opens reliably. A drop of light oil at the pivot helps keep it smooth.
Who provides the warranty, and where is it made?+
Warranty coverage is provided by the manufacturer, not Knifeworks. Contact the manufacturer for current warranty terms and service. Origin is listed in the product specifications on this page.
