The 12cm (133g) is more manoeuvrable and well suited to smaller prep tasks and ingredients. The 14cm (202g) is a mid-size option that works well as a daily workhorse for most kitchen tasks. The 17cm (221g) provides more blade length for larger ingredients and longer slicing strokes.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is Rockwell 57 hardness, and why does it matter?\u003c\/summary\u003e\n\u003cp\u003eRockwell hardness measures how resistant a steel is to deformation. Rockwell 57 sits in a range commonly used for professional kitchen knives - it holds an edge well for everyday use but remains soft enough to sharpen at home without specialist equipment. Harder steels (Rockwell 60 and above) hold an edge longer but can be more brittle and more difficult to maintain.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the Professional range differ from the Robert Welch Signature range?\u003c\/summary\u003e\n\u003cp\u003eBoth ranges use German DIN 1.4116 steel hardened to Rockwell 57. The Professional range features a larger, heavier handle and greater overall weight, designed for cooks who prefer a more substantial feel and balance in the hand. The Signature range is lighter and may suit those who prefer a more nimble knife.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is DuPont™ POM and how does it perform as a handle material?\u003c\/summary\u003e\n\u003cp\u003ePOM (polyoxymethylene) is a dense, engineering-grade polymer produced by DuPont. It is hard-wearing and moisture-resistant, provides a firm, tactile grip, and does not absorb odours or harbour bacteria in the way some natural handle materials can. It is well suited to frequent washing and daily kitchen use.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does a santoku knife differ from a standard chef's knife?\u003c\/summary\u003e\n\u003cp\u003eA santoku has a flatter cutting edge and a sheepsfoot-style tip, making it well suited to a push-cut or tap-chop technique rather than the rocking motion typically associated with a European chef's knife. It is a capable all-rounder for slicing, chopping and dicing, and many cooks find it particularly effective for fine vegetable prep.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does the scalloped blade actually do?\u003c\/summary\u003e\n\u003cp\u003eThe scallops (sometimes called a granton or hollow-ground edge) create small air pockets between the blade and food as you cut. This reduces the suction that causes thin slices to stick to the blade, and is particularly useful when slicing soft foods such as tomatoes, cucumbers or cooked meats. It is a functional rather than purely decorative feature.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"specs\" class=\"specs-box\"\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eSteel:\u003c\/strong\u003e German DIN 1.4116 stainless steel\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Fully forged, full tang\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e Rockwell 57 (ice-hardened)\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eEdge Angle:\u003c\/strong\u003e 15°\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eBlade Feature:\u003c\/strong\u003e Scalloped\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eHandle Material:\u003c\/strong\u003e DuPont™ POM\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eDishwasher Safe:\u003c\/strong\u003e Yes (hand washing recommended)\u003c\/div\u003e\n\u003cdiv class=\"spec-row\"\u003e\n\u003cstrong\u003eGuarantee:\u003c\/strong\u003e Robert Welch lifetime guarantee\u003c\/div\u003e\n\u003ch4\u003eSize Comparison\u003c\/h4\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eBlade Length\u003c\/th\u003e\n\u003cth\u003eOverall Length\u003c\/th\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e12cm \/ 4.5\"\u003c\/td\u003e\n\u003ctd\u003e120mm\u003c\/td\u003e\n\u003ctd\u003e232mm\u003c\/td\u003e\n\u003ctd\u003e133g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e14cm \/ 5.5\"\u003c\/td\u003e\n\u003ctd\u003e140mm\u003c\/td\u003e\n\u003ctd\u003e268mm\u003c\/td\u003e\n\u003ctd\u003e202g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e17cm \/ 7\"\u003c\/td\u003e\n\u003ctd\u003e170mm\u003c\/td\u003e\n\u003ctd\u003e298mm\u003c\/td\u003e\n\u003ctd\u003e221g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"guarantees\" class=\"trust-box\"\u003e\n\u003ch4 style=\"margin-top: 0; color: #2c5530; font-size: 18px;\"\u003eWhy Buy From Art of Living?\u003c\/h4\u003e\n\u003cp\u003eFounded in Reigate in 1972, we've spent over five decades helping customers select quality cookware and kitchen equipment.
