That first factory edge is just like the first tank of fuel that a new car comes with (or first charge of the battery).<br \/>\nA good factory edge is a &#8216;nice to have&#8217; but not a &#8216;make or break&#8217; for a good knife, as you will be putting your own edge onto it soon enough.<br \/>\nThe factory edge does however indicate the care a knife maker has put into the final finish.<br \/>\nIt is for this reason Tactical Reviews measures factory edge sharpness and specifications, and includes this information in the detailed technical testing.<\/p>\n<p>As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.<\/p>\n<p>In particular here, as we are focusing on the steel, the intention of the magnified edge images is in relation to the refinement of the edge that the steel allows.<\/p>\n<p>Spyderco&#8217;s consistency of factory edge and edge finishing is excellent, and these images confirm that the steel supports this very well.<\/p>\n<style type=\"text\/css\">\n#foogallery-gallery-15857 .fg-image { width: 150px; }\n#foogallery-gallery-15857 { --fg-gutter: 10px;

of specialist equipment, so as a basic and easy to understand test, I opted for a 1&#8243; manilla rope cut test with sharpness measurements.<\/p>\n<p>Once of the features of SPY27 that has been commented on is ease of maintenance, including with a strop, so while blunting it during the rope cut test, this would be followed by restoration of the edge by only a compound-loaded strop.<\/p>\n<p>The videos included below run through some of the stages of the test and the sharpness measurements. The videos also illustrate the cleanliness of cut and also show TV guide paper test cuts.<\/p>\n<p>Summarising the progression during the test, out of the box we have a BESS 178 edge (typically excellent Spyderco). This has become BESS 381 after 5 cuts, and after a total of 15 cuts measures BESS 378. Of note is that the BESS measurement is a spot check so repeated measurements can fluctuate slightly.<\/p>\n<style type=\"text\/css\">\n#foogallery-gallery-15867 .fg-image { width: 150px; }\n#foogallery-gallery-15867 { --fg-gutter: 10px; }<\/style>\n\t\t\t<div class=\"foogallery foogallery-container foogallery-default foogallery-lightbox-foobox fg-center fg-m-col2 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 fg-no-js\" id=\"foogallery-gallery-15867\" data-foogallery=\"{&quot;item&quot;:{&quot;showCaptionTitle&quot;:true,&quot;showCaptionDescription&quot;:true},&quot;lazy&quot;:true,&quot;src&quot;:&quot;src&quot;,&quot;srcset&quot;:&quot;srcset&quot;}\" style=\"--fg-title-line-clamp: 0; --fg-description-line-clamp: 0;\" >\n\t<div class=\"fg-item fg-type-image fg-loading\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2025\/12\/SPY27-17-cutting-P1014363.jpg\" data-attachment-id=\"15869\" data-caption-title=\"SPY27 17 cutting P1014363\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img src=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2025\/12\/SPY27-17-cutting-P1014363\/67910087.jpg\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" decoding=\"async\" loading=\"lazy\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><\/figure><div class=\"fg-loader\"><\/div><\/div><div class=\"fg-item fg-type-image fg-loading\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2025\/12\/SPY27-16-cutting-P1014355.jpg\" data-attachment-id=\"15868\" data-caption-title=\"SPY27 16 cutting P1014355\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img src=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2025\/12\/SPY27-16-cutting-P1014355\/1204602734.jpg\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" decoding=\"async\" loading=\"lazy\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><\/figure><div class=\"fg-loader\"><\/div><\/div><div class=\"fg-item fg-type-image fg-loading\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2025\/12\/SPY27-18-cutting-P1014387.jpg\" data-attachment-id=\"15841\" data-caption-title=\"SPY27 18 cutting P1014387\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img src=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2025\/12\/SPY27-18-cutting-P1014387\/471278977.jpg\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" decoding=\"async\" loading=\"lazy\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><\/figure><div class=\"fg-loader\"><\/div><\/div><div class=\"fg-item fg-type-image fg-loading\"><figure class=\"fg-item-inner\"><a href=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/2025\/12\/SPY27-19-post-cutting-strop-P1014423.jpg\" data-attachment-id=\"15870\" data-caption-title=\"SPY27 19 post cutting strop P1014423\" data-type=\"image\" class=\"fg-thumb\"><span class=\"fg-image-wrap\"><img src=\"https:\/\/tacticalreviews.co.uk\/wp\/wp-content\/uploads\/cache\/2025\/12\/SPY27-19-post-cutting-strop-P1014423\/3542834958.jpg\" width=\"150\" height=\"150\" class=\"skip-lazy fg-image\" decoding=\"async\" loading=\"lazy\"><\/span><span class=\"fg-image-overlay\"><\/span><\/a><\/figure><div class=\"fg-loader\"><\/div><\/div><\/div>\n\n<hr color=\"#333333\"><\/hr>\n<p>The used edge was then worked on a strop loaded with a fine metal polishing compound, and without any re-sharpening, just using this strop, the edge was brought to BESS 179.

Being the first article dedicated to a steel, I can only conclude that the results of the testing employed for this article will give us a reference result for edge stability to compare others to. The figures show the degree of blunting from a common cutting test, and that after the initial blunting the blade continued to cut well.<\/p>\n<p>Perhaps the most pleasing result was the full edge sharpness recovery by stropping alone. Of course most blunting is caused by rolling the edge apex, so stropping is effective to realign this, but here we have a perfect recovery after 15 1&#8243; manilla rope cuts.<\/p>\n<p><b>Review Videos<\/b><\/p>\n<p>This mini series consists of three short form videos showing a 1&#8243; manilla rope cut test with sharpness measurements:<\/p>\n<div class=\"video-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/xdyowBGf05M?rel=0\" frameborder=\"0\" allowfullscreen><\/iframe><\/div>\n<hr color=\"#333333\"><\/hr>\n<div class=\"video-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/ZuYINA2rb6U?rel=0\" frameborder=\"0\" allowfullscreen><\/iframe><\/div>\n<hr color=\"#333333\"><\/hr>\n<div class=\"video-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/h9pULq2QYB8?rel=0\" frameborder=\"0\" allowfullscreen><\/iframe><\/div>\n<hr color=\"#333333\"><\/hr>\n<p>&nbsp;<br \/>\n<b>Discussing the Review:<\/b><br \/>\nSomething new &#8211; will it work?
