Product Insights

The Opinel Parallèle No. 121 is an in-stock 74 CAD fillet knife built around an 18 cm X50CrMoV15 stainless blade at 56–57 HRC with a 2 mm progressive-flex profile: stiff at the heel for controlled cuts through bones and pliable in the tip third for rib cages and belly flesh, while the slender curved tip slips under pin bones and opens cuts behind the fins without tearing flesh and the heel finishes long passes, covering small panfish to 5-pound salmon in continuous single-pass cuts rather than sawing. Its full-tang construction is pinned through a lacquered/varnished beech handle with two rivets and shifts weight to the handle for reduced fatigue and improved tip control; the ergonomic guarded grip stays steady when wet. The symmetric 50/50 double-bevel grind and symmetric double-bevel edge geometry make it equally usable for left- and right-handed filleters, and the high-chromium stainless steel resists rust from wet fish and washing while resharpening in a few passes on a rod or stone. The main tradeoff is the varnished beech handle, which requires hand washing and drying plus occasional food-safe wood oil; the knife otherwise follows Opinel's 1897 numbering and No.08 silhouette and matches the 7-inch full-flex fillet category default.
