The Sinnsyk (Current Lead Time is 16-18+/- Months)

Sinnsyk (sin-sick) means Insane/Crazy in Norwegian, and you can see the inspiration as to why we chose that name.

A few months ago, Shane developed a challenge for himself to create a new knife design every day for 75 days. After the challenge was complete, we hosting a vote to decide which folding knife was the favorite… The Sinnsyk was the clear winner.

Blade: The Sinnsyk features a spear-point style hand ground blade with a hollow ground top swedge and hollow ground main bevel. The grinding or stock removal of the steel on the blade is achieved on a 2×72 vertical knife grinder. The blade is then prepared, and heat treated in house to maintain quality and precision during such a crucial and often overlooked step of the process.  The opening action is found on a thumb-stud in the blade that fires the blade open on caged ceramic ball bearings.

Handles: The handles on the Sinnsyk are made from US made Aerospace Grade 5 6AL4V Titanium. This grade of titanium allows for the proper function of the lock bar as well as more accurate machining and overall, more dependable outcome for the mechanics and finishes. The Sinnsyk features a slender yet strong handle design with .160″ thick material. All the machining, sanding, sculpting, and customizing is done in house by hand individually for every part on the knife.

Clip and Hardware: The clip is made from the same trusted 6Al4V titanium as the handles and is machined and hand finished to give the right tension in the pocket without compromising on looks or quality. The Sinnsyk also features a hardened stainless steel glass breaker with jimping on the spine for better grip. The hardware is US made from titanium using a precision Swiss Screw machine. The hardened precision pivot barrel features a .250 outside diameter to ensure the strongest hinge-point for the blade without compromising the integrity of the blade strength.  Holding the pivot and knife assembly together are titanium pivot screws on both sides.
