Possible limitations
Higher weight – approx. 221 g – more noticeable in the pocket than lighter EDC models.
D2 steel is not fully stainless – it requires regular cleaning and corrosion protection when exposed to moisture.
The OTF mechanism is more sensitive to dirt than a classic manual folding mechanism and requires regular maintenance.
The aluminum handle is strong, but can show cosmetic wear and scratches during hard use.
The Winter Digi design is bold and may not suit users who prefer a simple or discreet appearance.
The glass breaker increases the knife’s length and weight and may make it less comfortable to carry.
Legal restrictions – carrying and using automatic knives may vary by country and situation according to applicable regulations.
Maintenance and care
After use, clean the blade from dirt and dry it thoroughly.
Regularly treat the D2 steel with a thin layer of suitable preservative oil, especially after exposure to moisture.
Keep the OTF mechanism clean and protect it from dust, sand, and other contaminants.
Lubricate the moving parts of the mechanism lightly as needed with oil designed for knives and fine mechanisms. Do not use excessive amounts of oil.
Clean the aluminum handle with a soft cloth and a mild cleaning agent. Avoid aggressive chemicals.
Keep the glass breaker clean and check that it is securely attached.
Store the knife in a dry place, ideally away from prolonged moisture exposure.
Maintain the edge regularly with a suitable sharpening system. We recommend the Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF.
