The\u00a0<strong>new design\u00a0<\/strong>provides greater rigidity in holding the horizontal position of the frame and allows only 0.1\u00b0 of arm deflection at a force of 30N.<\/p>\n<p>A screw at the back of the turning mechanism allows you to adjust the force required to flip the clamping arm.<\/p>\n<p>The ability to fully lock the flip will be useful during the reprofiling of the knife when it is subjected to heavy loads and vibrations, as well as when sharpening particularly long blades, when additional protection against accidental flipping is needed.<\/p>\n<p>Three-stage angle adjustment<\/p>\n<p>The K4 rack and pinion height adjuster allows easy, fast, and precise setting of the sharpening angle.<\/p>\n<p>Locking of moving elements of the unit can be done with one hand and ensures reliable locking in the desired position.<\/p>\n<p>The new angle setting mechanism has\u00a0<strong>three adjustment levels<\/strong>:<br \/>\n&#8211;\u00a0<strong>rough\u00a0<\/strong>adjustment (accuracy\u00a0<strong>up to 1\u00b0<\/strong>) with an extendable slider;<br \/>\n&#8211;\u00a0<strong>fine<\/strong>\u00a0adjustment (<strong>up to 0.1\u00b0<\/strong>) with a rack and pinion mechanism;<br \/>\n&#8211;\u00a0<strong>ultra-fine<\/strong>\u00a0adjustment (<strong>up to 0.01\u00b0<\/strong>) with the micro-adjustment unit.<\/p>\n<p>The\u00a0<strong>micro-adjustment unit<\/strong>\u00a0allows you to change the angle with maximum precision, which is particularly useful for deburring and working with the finest abrasives.<\/p>\n<p>The arrangement of the sharpening system parts allows you to set the sharpening angle in the range from<strong>\u00a09\u00b0 to 39.5\u00b0 per side<\/strong>, for knives up to 430 mm in length.<\/p>\n<p>Thickness compensator<\/p>\n<p>The height adjuster is equipped with a removable stone thickness compensator. It provides a quick adjustment of the angle during stone change.<\/p>\n<p>Abrasive holder<\/p>\n<p>A brand\u00a0<strong>new method of mounting<\/strong>\u00a0the stroke\u00a0<strong>limiters\u00a0<\/strong>and the\u00a0<strong>coupling\u00a0<\/strong>on the rod provides increased mounting security and ensures immobility of the elements during operation.<\/p>\n<p>Instead of point locking with a screw, the mechanism now uses surface locking through cylindrical sleeves with holes. This reduces the force required to secure the elements and eliminates the possibility of the rod surface damage.<\/p>\n<p>The front abrasive stop provides convenient abrasive mounting. It features a spring-loaded ball screw, which prevents free rotation of the stop on the rod and ensures smooth running.<\/p>\n<p>The hinge unit incorporates a stainless steel-brass sliding pair for smooth rod travel during use.<\/p>\n<p>Rod parking<\/p>\n<p data-end=\"715\" data-start=\"470\">The K4 carries over the stroke limiter and L-shaped piece from the K03, while introducing an upgraded parking system. With subtle refinements to the kinematic scheme, it delivers greater ease of use.<\/p>\n<p>New detachable Axicube Shift<\/p>\n<p>Now\u00a0<strong>Axicube Shift sits on the far abrasive stop<\/strong>. It can be quickly and easily removed to reduce abrasive weight during sharpening and for easy charging away from the sharpening system. Far and close abrasive stops&#8217; positions are interchangeable.<\/p>\n<p>The\u00a0<strong>new mounting<\/strong><strong>, featuring a special rail<\/strong>\u00a0in combination with a locking screw and a magnet, provides an\u00a0easy and secure attachment of the angle finder for accurate measurement of the sharpening angle. Axicube-i can be charged via\u00a0<strong>USB Type-C<\/strong>\u00a0cable.<\/p>\n<p>Quick clamps<\/p>\n<p data-pm-slice=\"1 1 []\">The Quick clamps securely hold knives up to 7 mm thick. They provide a fast and tool-free usage and a 300 N clamping force. Designed with finite element analysis, the clamps&#8217; structure evenly distributes stress for uniform jaw closure.<\/p>\n<p>Removable clamping arm<\/p>\n<p data-pm-slice=\"1 1 []\">Fancy a microscope edge inspection? The new removable design of the clamping arm will become your favorite feature of the K4. No need to take the knife out of the clamps or try and repeat its position and set the same sharpening angle anymore.<\/p>\n<p>Rigid body and stable base<\/p>\n<p data-pm-slice=\"0 0 []\">The fresh design of the leg enhances the portability of the sharpener and allows you to carry it easily with one hand. It attaches to the milled base with three rigid quick-release screws. Thanks to its shape, weight, and wide, slim shock absorbers, the system remains stable during sharpening.<\/p>\n<p>Kit includes<\/p>\n<ul>\n<li>TSPROF \u041a4 body with integrated base<\/li>\n<li>TSPROF abrasive holder with detachable electronic angle finder Axicube Shift<\/li>\n<li>TSPROF Quick clamps, black &#8211; 2 pcs.<\/li>\n<li>Spare parts<\/li>\n<li>Packaging: wooden box with a foam insert<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>\u2022 TSPROF K4 &#8211; is the most sophisticated and innovative knife sharpener of the line.<br \/>\n\u2022 Axicube Shift &#8211; a new built-in electronic angle finder.
