Zero Tolerance ZT 0357 handle scales

The Zero Tolerance 0357 (often called ZT 0357) is a rugged, USA-made assisted-opening folder designed as an accessible, hard-working EDC that delivers premium performance at a more approachable price

Zero Tolerance, launched in 2006 by Kai USA, built its reputation on overbuilt tactical knives for military, law enforcement, and first responders—starting with heavy-duty models like the 0300 (2006) and iconic 0350 (2009, Ken Onion design)

By 2020, ZT sought to expand its lineup with a "premium made simple" workhorse: in-house designed (ZT Originals), blending 0350-style assisted action with modern upgrades. The ZT 0357 was announced in early 2020 (KnifeNews March 2020 coverage; official release 2020 per ZT site)

Key features: 3.25" CPM 20CV (later S45VN) drop-point blade (working or BlackWash finish for scratch hiding), textured black G-10 scales over stainless liners, SpeedSafe assisted flipper, liner lock, four-position clip, and 4.3 oz build—USA-made in Oregon for durability and smooth deployment

Priced ~$150–$245 MSRP, it earned quick acclaim as a no-nonsense everyday tool with exceptional edge retention and grip—ideal for work, outdoor, or tactical use. Variants (e.g., 0357BW BlackWash) followed, reinforcing ZT's blend of heritage toughness and practical innovation
