F. Dick ErgoGrip 15 cm (5.9 in) flexible boning knife review
The only knife in this hub that publishes both its steel designation and its hardness: X55CrMo14 at a stated 56 HRC, flexible, with a curved blade that lengthens the cutting stroke.
What we would actually buy The most completely specified knife in this hub, from a maker who sells to butchers. The flex is the property to check against your own use.
What you are getting
A 15 cm (5.9 in) flexible boning knife in X55CrMo14 stainless stated at 56 HRC, with a curved blade and an ErgoGrip handle.
The published figures
Steel designation and hardness, both. 56 HRC is the softer European convention: the edge rolls rather than chips, comes back on a steel in seconds, and will need that steel often.
The curve
F. Dick explain it on the listing: a curved edge is longer than a straight one of the same blade length, which allows a long drawing cut. It is also the shape that follows the contour of a bone.
The flex
Flexible, which suits fish, poultry and trimming. For driving between the joints of a large animal, a stiff blade is the right tool and this is not it.
Availability
On sale at around $23 on the American Amazon store at the time of checking.

A professional butchery brand at the entry price of this hub
Compromises

The molded handle is functional rather than beautiful

The questions that come in
Flexible or stiff?
Flexible follows a ribcage and lifts a fillet; stiff drives between joints without wandering. This one is flexible, which suits fish and poultry more than heavy jointing.
Why is the blade curved?
F. Dick states that the curve makes the edge longer than a straight blade of the same length, which allows a long drawing cut. It is also what lets the tip follow a bone.
