In an attempt to produce truly unbiased information that can be used to directly compare different knives, Tactical Reviews introduced a variety of measurements and technical tests, in some cases pioneering previously unseen methods and tests to develop a knife technical testing methodology.<\/p>\n<p>This level of technical testing, originated by Tactical Reviews, takes things far beyond manufacturer&#8217;s knife specifications, and has developed to a point it needs its own page of information to explain how it&#8217;s done.<\/p>\n<p>This page will evolve over time as new tests and extra information are added.<\/p>\n<hr color=\"#333333\"><\/hr>\n<h3>The Blade and Handle &#8211; Detailed Measurements:<\/h3>\n<p>For each knife tested I carry out a detailed examination of geometry, balance, edge bevels, factory sharpness and structural edge testing using the industry leading measuring tools.<\/p>\n<p>These measuring tools include a Vernier protractor, callipers, fixed radius gauges, the unique Arc Master adjustable radius gauge, Edge On Up&#8217;s BESS Certified PT50A and SET tester, along with CATRA&#8217;s Hobbigoni LASER Edge Protractor.<\/p>\n<p>This first gallery shows some of those measurements being taken.<\/p>\n<style type=\"text\/css\">\n#foogallery-gallery-8172 .fg-image { width: 150px; }\n#foogallery-gallery-8172 { --fg-gutter: 10px;

Using a PT50A BESS Certified sharpness tester:<\/h3>\n<p>The BESS &#8216;C&#8217; scale of sharpness, developed by Mike Brubacher (Brubacher Edge Sharpness Scale) is used to determine how sharp each knife edge is. The &#8216;Edge on Up&#8217; PT50A tester uses a certified test media fibre and records the force required to cut it. The lower the score the better. As an example, a typical Morakniv factory edge scores around 250. This test will be used to verify the sharpness of the factory edge and allow the knife to be brought to a minimum standard sharpness before testing a blade&#8217;s cutting performance.<\/p>\n<style

Table:<\/h3>\n<p>All the measurements are tabulated and are presented along with a few reference blades.<\/p>\n<p>To confirm the manufacturers specifications, a number of basic measurements are taken. These include Weight with Sheath (g), Weight (g), Overall Length (mm), Grind, Blade Length (mm), Blade Thickness Max (mm), Handle thickness &#8211; Max (mm) and Handle Depth &#8211; Max (mm).<\/p>\n<p>Taking a specific UK check, for UK EDC legal knives there is a check of the Cutting Edge Length &#8211; (mm). Based on experiences and practices used by police officers, this is a measurement taken by rolling the edge along a scale to include the actual edge length, not a straight line from heel to tip.<\/p>\n<p>Balance is a critical factor for the feel of a knife so the Balance point is found and measured from the tip (mm). The &#8216;Balance relative to the front of the handle&#8217; tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The &#8216;Balance relative to the centre of the handle&#8217; indicates how close to a &#8216;neutral balance&#8217; the knife has in the hand.<\/p>\n<p>Taking a more detailed examination of the geometry of the blade involves measurements not normally included by the manufacturer. These include Grind Radius inch\/mm (for hollow ground blades), Grind Length, Blade Depth &#8211; Max (mm), Blade Flat depth @ Max Depth (mm) and Primary Bevel Included Angle (DD\u00b0 MM&#8217; SS&#8221;).<\/p>\n<p>A factory edge is only a starting point, but this is examined on all test knives to check for consistency and to provide a reference point for what the factory decided was right for the knife. The measurements are; Total Factory Edge Bevel Angle (DD\u00b0), Right-hand Factory Edge Bevel Angle (DD\u00b0) and Left-hand Factory Edge Bevel Angle (DD\u00b0).<\/p>\n<p>For an indication of piercing ability and eagerness, the Point angle and Secondary Point Angle (American Tanto) are included.<\/p>\n<p>Whatever sharpness the blade has, and whatever edge angle is used, a critical factor in slicing ability and ease of deep cutting is the Thickness behind the edge (mm). This will tell you how much, or how little, material the blade needs to push out of the way.<\/p>\n<p>The last measurement is Rake &#8211; Handle to blade angle (approx) up is -ve. This tells you how the blade will present itself in your hand, and how it will behave in slicing, piercing and chopping cuts.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-parametersV1b.jpg\" alt=\"\" width=\"1849\" height=\"1186\" class=\"aligncenter size-full wp-image-8484\" srcset=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-parametersV1b.jpg 1849w, https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-parametersV1b-600x385.jpg 600w, https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-parametersV1b-300x192.jpg 300w, https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-parametersV1b-768x493.jpg 768w, https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-parametersV1b-1024x657.jpg 1024w\" sizes=\"auto, (max-width: 1849px) 100vw, 1849px\" \/><\/p>\n<hr color=\"#333333\"><\/hr>\n<h3>Structural Edge Testing:<\/h3>\n<p>Added in 2019 are results from the Edge On Up Structural Edge Tester (SET) to measure the resistance of a knife&#8217;s edge to rolling.<\/p>\n<p>The key factors for the SET results are:<br \/>\nSeries 1 Degradation &#8211; how much damage the edge suffers from one edge rolling cycle.

familiar with fixed blades and locking knives, using a slip-joint knife safely requires familiarity with the appropriate cutting technique, ensuring you only apply pressure in a direction that keeps the blade open. Though it should never be relied upon, an important aspect of a slip-joint knife&#8217;s design is the strength of the spring, and so the blade&#8217;s resistance to closing.<\/p>\n<p>As the length of the blade, and point at which force is applied to close the blade, will both vary, the measurements here will be presented as a torque value in Nm (newton-metre). This presents a universal value of turning force that can be used for direct comparison of different slip-joint designs.<\/p>\n<p>In some cases, the torque required to open the blade is also measured (to see how opening and closing torque compares); this whole test was inspired by the Chris Reeve Knives &#8216;Impinda&#8217; and its Bill Harsey design that needs significantly more force to close the blade than open it.<\/p>\n<p>Included in the table of values are the raw measurements, and two reference knives, a typical Victorinox, and a custom slip-joint made by &#8216;Shing&#8217;, known for the spring strength. The review knife (in this example a Viper Dan) is then shown with the reference values.<\/p>\n<style type=\"text\/css\">\n#foogallery-gallery-8490 .fg-image { width: 150px; }\n#foogallery-gallery-8490 { --fg-gutter: 10px; }<\/style>\n\t\t\t<div class=\"foogallery foogallery-container foogallery-default foogallery-lightbox-foobox fg-center fg-default fg-ready fg-dark fg-border-thin fg-round-medium fg-loading-default fg-loaded-fade-in fg-caption-hover fg-hover-fade fg-hover-zoom\" id=\"foogallery-gallery-8490\" data-foogallery=\"{&quot;item&quot;:{&quot;showCaptionTitle&quot;:true,&quot;showCaptionDescription&quot;:true},&quot;lazy&quot;:true}\" style=\"--fg-title-line-clamp: 0; --fg-description-line-clamp: 0;\" >\n\t<div class=\"fg-item fg-type-image fg-idle\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/TorqueV2.jpg\" data-caption-title=\"Closing torque.\" data-caption-desc=\"Closing torque.\" data-attachment-id=\"8492\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img decoding=\"async\" title=\"Closing torque.\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" data-src-fg=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2019\/12\/TorqueV2\/981280922.jpg\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%22150%22%20height%3D%22150%22%20viewBox%3D%220%200%20150%20150%22%3E%3C%2Fsvg%3E\" loading=\"eager\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><figcaption class=\"fg-caption\"><div class=\"fg-caption-inner\"><div class=\"fg-caption-desc\">Closing torque.<\/div><\/div><\/figcaption><\/figure><div class=\"fg-loader\"><\/div><\/div><div class=\"fg-item fg-type-image fg-idle\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/TorquePullV2.jpg\" data-caption-title=\"Opening torque.\" data-caption-desc=\"Opening torque.\" data-attachment-id=\"8491\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img decoding=\"async\" title=\"Opening torque.\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" data-src-fg=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2019\/12\/TorquePullV2\/4271081257.jpg\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%22150%22%20height%3D%22150%22%20viewBox%3D%220%200%20150%20150%22%3E%3C%2Fsvg%3E\" loading=\"eager\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><figcaption class=\"fg-caption\"><div class=\"fg-caption-inner\"><div class=\"fg-caption-desc\">Opening torque.<\/div><\/div><\/figcaption><\/figure><div class=\"fg-loader\"><\/div><\/div><div class=\"fg-item fg-type-image fg-idle\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2019\/12\/Dan-Torque.jpg\" data-attachment-id=\"8493\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img decoding=\"async\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" data-src-fg=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2019\/12\/Dan-Torque\/3358504019.jpg\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%22150%22%20height%3D%22150%22%20viewBox%3D%220%200%20150%20150%22%3E%3C%2Fsvg%3E\" loading=\"eager\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><\/figure><div class=\"fg-loader\"><\/div><\/div><\/div>\n\n<hr color=\"#333333\"><\/hr>\n","protected":false},"excerpt":{"rendered":"<p>When testing knives there are many different aspects to consider.
