How the Five Compare on the Numbers
Four of the five carving knives on this sheet publish a 12 inch blade: the Cutluxe, the Rondauno, the HOSHANHO and the Sunnecko slicer. The Brewin set publishes no blade length for any of its three knives, so it cannot be compared on that figure. The Cutluxe publishes a depth of 17.0 inches against 16.7 inches for the Rondauno. The HOSHANHO field reads 9.84 inches, which cannot be a 12 inch knife, so it reads as the box rather than the blade.
Published hardness separates the group. The Sunnecko states 58+ Rockwell, the Cutluxe and Brewin state 56+, and the Rondauno and HOSHANHO state no hardness figure at all. Edge angles are published by four makers: 15 degrees for the HOSHANHO, 14 to 16 degrees per side for the Cutluxe and Brewin, and 12 to 15 degrees per side for the Sunnecko.
The table does not tell you how any of these knives feels in the hand, how long an edge lasts, or how the steel behaves after repeated washing. None of that is published, and nobody at Lush has used these knives. The figures above are what the makers state, nothing more.
Blade Length and What It Covers
The case for a 12 inch blade
A 12 inch blade is the length most often published on this sheet, and it is the figure that decides whether a knife can cross a whole brisket in one stroke. The Cutluxe, the Rondauno, the HOSHANHO and the Sunnecko slicer all state 12 inches in their own text. The HOSHANHO also carries a size field reading 11.6 inches, which its own title contradicts, so this page uses the title.
For a roast or a turkey, that difference is unlikely to matter. For a full packer brisket, a longer blade lets the cut finish before the tip leaves the meat. The Brewin set publishes no blade length, so a reader shopping for a dedicated brisket slicer cannot confirm what they are getting from the sheet alone.
What the shorter and longer figures mean
The HOSHANHO is where the two published figures disagree. Its title and its feature text say 12 inches while its size field says 11.6 inches, and nothing in the listing reconciles them. The maker describes the knife as suitable for substantial meat portions and for large fruit such as watermelon, which is a broader brief than a pure brisket slicer.
The Cutluxe publishes a depth of 17.0 inches against 16.7 inches for the Rondauno, a gap of 0.3 inches. Both figures are longer than the 12 inch blade each one states, so both include a handle and probably a sheath. Neither maker says what the field measures, and 0.3 inches is small enough that no buyer would notice it in a drawer.
Steel, Hardness and Edge Angle
What each maker states about the steel
The Cutluxe states high carbon German steel at 56+ Rockwell. The Brewin states 1.41 German stainless steel, also at 56+ Rockwell. The Sunnecko states high carbon steel at 58+ Rockwell against 56+ for the other two that publish one. The Rondauno states 5Cr15Mov high carbon stainless steel and the HOSHANHO states Japanese 10Cr15CoMoV, but neither publishes a hardness figure.
Hardness figures are not comparable across makers unless the same scale and the same test method are used, and the sheet does not say how any of these numbers were obtained. Treat 56+ and 58+ as what the makers state, not as a ranking of edge life.
Edge angles as published
The HOSHANHO publishes a 15 degree edge, described as calibrated to reduce cutting resistance. The Cutluxe and the Brewin both publish 14 to 16 degrees per side. The Sunnecko publishes 12 to 15 degrees per side across its two knives. The Rondauno publishes no edge angle.
A more acute angle is generally thinner behind the edge, but the sheet gives no measurement of blade thickness for any of the five, so the angles cannot be tied to a physical cross section. What the figures do show is that the Sunnecko states the widest range and the HOSHANHO states a single figure.
Sets, Single Knives and Handles
Single knives against sets
Three of the five are single carving knives: the Cutluxe, the Rondauno and the HOSHANHO. The Sunnecko is a two knife set with a 12 inch slicer and a 7 inch boning knife, plus a sheath and a small kitchen tweezer. The Brewin is a three knife set with a chef knife, a santoku and a utility knife.
If the job is carving a roast at the table, a single long slicer is the direct answer. If the job also includes trimming a whole brisket before cooking, the Sunnecko set covers both with its boning knife. The Brewin set covers general kitchen prep rather than carving specifically.
Handle materials and published weights
The Cutluxe and the Sunnecko both state pakkawood handles. The Brewin states a triple riveted ABS handle. The Rondauno and the HOSHANHO describe ergonomic handles without naming a material. Four of the five publish a weight: the Rondauno at 0.4 lb, the Cutluxe at 0.6 lb, the Brewin at 1.87 lb and the Sunnecko at 2.18 lb.
The Rondauno is the lightest of those four at 0.4 lb and the Sunnecko the heaviest at 2.18 lb, but the Sunnecko figure covers two knives, a sheath and a tweezer, so it is not the weight of the slicer alone. The Brewin 1.87 lb covers three knives and a gift box. The HOSHANHO publishes no weight at all, which leaves two of the five with a figure that belongs to one knife.
Which One Fits Your Kitchen
You carve whole briskets and large roasts. The Cutluxe publishes a 12 inch Granton blade in German steel at 56+ Rockwell, with a pakkawood handle and a sheath. Its depth field reads 17.0 inches against 16.7 inches for the Rondauno.
You want the lightest knife in hand. The Rondauno publishes 0.4 lb against 0.6 lb for the Cutluxe, a difference of 0.2 lb, and carries a 12 inch 5Cr15Mov blade. It states no hardness figure and no edge angle.
You prefer Japanese steel and a single acute edge. The HOSHANHO publishes 10Cr15CoMoV steel and a 15 degree edge, with a 12 inch blade in its title. Its size field says 11.6 inches instead, and the maker publishes no weight at all.
You trim and carve with the same purchase. The Sunnecko set pairs a 12 inch slicer with a 7 inch boning knife, both hand sharpened at 12 to 15 degrees per side, and states 58+ Rockwell against 56+ for the Cutluxe and the Brewin.
You want one box for general kitchen prep. The Brewin set gives a chef knife, a santoku and a utility knife in 1.41 German steel at 56+ Rockwell. It publishes no carving blade length, so it is not a dedicated brisket slicer.
What We Could Not Verify
The fact sheet leaves several figures unstated. These are the ones a buyer would most want and that no maker on this list publishes.
- Blade thickness for any of the five knives.
- The weight of any single knife inside the Sunnecko and Brewin sets, as opposed to the packed box.
- A Rockwell hardness figure for the Rondauno and the HOSHANHO.
- An edge angle for the Rondauno.
- The handle material on the Rondauno and the HOSHANHO, both described only as ergonomic.
- Any measurement of how long an edge holds up in use, which no maker states.
