EDGE LAB B Sharpness Tester A precision instrument designed for sharpening professionals and enthusiasts, combining sharpness and slicing analysis in one system. Capacity 3000 g range The EDGE LAB B supports measurements up to 3000 grams (6.5 lb) while maintaining precise 1 gram resolution. Precision Accurate readings Designed for reliable and repeatable results, ideal for both professional sharpening workflows and advanced hobby use. Warranty 3-year coverage Backed by a 3-year limited warranty for long-term reliability and consistent performance. Overview See EDGE LAB in action Watch how EDGE LAB measures both push-cut sharpness and slicing performance with detailed data output. Testing modes Sharpness and slicing EDGE LAB operates in two modes: MAX (sharpness) and SLC (slicing), allowing both push-cut and slicing analysis. Slice test media supports both push and slicing tests, generating dozens of data points per measurement. Slice test media is a 0.010" (0.25 mm) polymer, available in SLCTM20 and SLCTM30 configurations. It enables direct comparison with other sharpeners and established edge standards. Each test — push or slice — generates dozens of logged data points, compared to a single data point in standard sharpness testing. Analysis Deeper edge insight EDGE LAB allows direct comparison of edge types and geometry, clearly showing how blade design affects cutting performance. It provides objective answers to long-standing sharpening questions. Flexibility Test real materials In addition to standard media, you can test paper, rubber, and other flexible materials up to 2 mm thick. Slicing tests may be conducted manually with the included SLCF20 test fixture or with the aid of one of our Slice accessories. Software Data and export The included Windows interface allows parameter setup, average force calculation, and CSV export for further analysis. Data can be used in Excel for graphing and advanced evaluation. Included Essential kit The package includes a Standard User Software Interface with CSV file support, an RS232/USB cable interface, and SLF20 & ATF10G media fixtures for up to 125 sharpness tests. It also comes with 50 SLT30 slice test media for approximately 100 slicing tests, a KFL10R knife fulcrum, and a rechargeable battery with AC/DC wall charger and power supply. Compatibility Expandable system Fully compatible with EDGE LAB accessories and PT50 test media formats for extended testing capabilities. EDGE LAB combines sharpness and slicing data into a comprehensive evaluation of edge performance. It reflects how a blade performs in real-world use — in the kitchen or industrial environments. .r2-case-apple{color:#191919;line-height:1.5} .r2-case-apple *,.r2-case-apple *::before,.r2-case-apple *::after{box-sizing:border-box;font-family:inherit!important} .r2-case-apple img{display:block;width:100%;height:auto;border:0;border-radius:24px} .r2-case-apple section{margin:0 0 20px} /* HERO */ .r2-hero{text-align:center;padding:12px 0 4px} .r2-hero-copy{max-width:760px;margin:0 auto 18px} .r2-hero-media{max-width:520px;margin:0 auto} .r2-hero h1{ margin:0 0 12px; font-weight:700; letter-spacing:-0.02em; font-family:'Montserrat',sans-serif!important; color:inherit; } @media(min-width:575px){ body .r2-case-apple .r2-hero .r2-hero-copy h1.hero-text{ font-size:36px!important; line-height:50px!important; } } .r2-subtitle{ max-width:720px; margin:0 auto; font-size:19px; line-height:1.4; color:#6e6e73; } /* LABELS */ .r2-case-apple .r2-feature-card p.r2-card-label, .r2-case-apple .r2-split-copy p.r2-card-label, .r2-case-apple .r2-showcase-copy p.r2-card-label{ margin:0 0 8px; font-size:12px!important; line-height:1.2!important; font-weight:700!important; letter-spacing:.06em!important; text-transform:uppercase; color:#6e6e73!important; font-family:'Montserrat',sans-serif!important; } /* FEATURES */ .r2-feature-grid{display:grid;gap:16px} .r2-feature-grid-3{grid-template-columns:repeat(3,1fr)} .r2-feature-grid-2{grid-template-columns:repeat(2,1fr)} .r2-feature-card{ background:#f5f5f7; border-radius:24px; padding:24px; } .r2-feature-card h2, .r2-split-copy h2, .r2-showcase-copy h2{ margin:0 0 8px; padding-bottom:0!important; font-size:26px; line-height:1.15; font-weight:700; letter-spacing:-0.02em; color:#191919; } .r2-split-copy h2{ font-size:28px; } .r2-feature-card p, .r2-split-copy p, .r2-showcase-copy p{ margin:0; font-size:16px; line-height:1.45; color:#373e48; } .r2-feature-card p + p, .r2-split-copy p + p, .r2-showcase-copy p + p{ margin-top:10px; } /* VIDEO */ .r2-showcase-video{ display:grid; grid-template-columns:.95fr 1.05fr; gap:24px; align-items:center; background:linear-gradient(180deg,#fbfbfd 0%,#f5f5f7 100%); border-radius:32px; padding:28px; overflow:hidden; } .r2-video-wrap{width:100%} .r2-video-frame{ position:relative; width:100%; padding-top:56.25%; border-radius:22px; overflow:hidden; background:#000; } .r2-video-frame iframe{ position:absolute; inset:0; width:100%; height:100%; border:0; display:block; } /* SPLIT */ .r2-split{ display:grid; grid-template-columns:1fr .9fr; gap:24px; align-items:center; background:#fbfbfd; border-radius:28px; padding:28px; } .r2-split-copy{max-width:520px} .r2-split-media{ width:100%; max-width:420px; margin:0 auto; } .r2-split-media img{ width:100%; border-radius:22px; } /* MOBILE */ @media(max-width:989px){ .r2-feature-grid-3, .r2-feature-grid-2, .r2-showcase-video, .r2-split{ grid-template-columns:1fr; } .r2-split{ padding:22px; gap:18px; } .r2-split-copy{ max-width:100%; } .r2-split-copy h2{ font-size:24px; } .r2-split-media{ max-width:100%; } } @media(max-width:749px){ .r2-feature-card, .r2-showcase-video, .r2-split{ padding:18px; } .r2-subtitle{ font-size:17px; } .r2-split-copy h2{ font-size:22px; } }
