They\u2019ve got loupes and microscopes, but also Fresnel lenses, commercial grade front-side mirrors, laser parts, optical bench gear, prisms, and advance fiber optic stuff \u2014 just about anything optical you can imagine at good prices, Anchor sells Edmund\u2019s surplus or \u201cseconds\u201d \u2014 but only second in some cosmetic or inessential way.

As someone who has more experience with camera lenses than loupes, I didn\u2019t know what to expect. What arrived was an immaculately crafted magnifying device that I now carry on a daily basis.<\/p>\n\n\n\n<p>Built by the Belarus Optical and Mechanical Enterprise Company (they once made high quality optics for the Soviet Union during the Cold War), the minuscule 10x loupe radiates a quality of craft and \u201cthingness\u201d that I\u2019ve previously only seen in Leica glass. This comparison is in part owed to the superb optics, but also to the textured black enamel that coats the folding steel case coupled with its solid build quality.<\/p>\n\n\n\n<p>The loupe itself is compact, quick to fold out, and easy to use. Between using it to identify mushrooms, to seeing the destruction I wreak on my fingernails, or the dulled edge of my kitchen knives, I have found the ability to easily magnify anything 10x (or more) has given me a renewed appreciation for the smaller things in life.<\/p>\n\n\n\n<p>My decision to pick up the 10x magnification instead of the 15x or 20x was driven by cost and usability. Everyone I spoke to seemed to agree that 10x had the best balance between field of view, depth of field, and cost. Unlike other loupes where you can change magnification through opening up additional lenses, the Belomo relies on a single lens system that reduces the chance of breaking, while providing greater optical quality and increased light. The image quality is really fantastic.<\/p>\n\n\n\n<p>One of the best features of the Belomo Loupe is the ability to incorporate it as an external macro lens with my iPhone camera. The small sensor size coupled with the Loupe means that it has enough depth of field to create photos I can use to identify when I get home. I\u2019ve been blown away with the results.<\/p>\n\n\n\n<p>The Belomo loupe is a fantastic EDC tool that provides a new way to look at the world. I can\u2019t recommend it enough. \u2014&nbsp;<em>Oliver Hulland<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/kk.org\/cooltools\/files\/2026\/07\/El-Wire-1024x1017.jpg\" alt=\"\" class=\"wp-image-46425\" width=\"344\" height=\"342\" srcset=\"https:\/\/kk.org\/cooltools\/files\/2026\/07\/El-Wire-1024x1017.jpg 1024w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/El-Wire-300x298.jpg 300w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/El-Wire-150x150.jpg 150w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/El-Wire-768x762.jpg 768w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/El-Wire.jpg 1100w\" sizes=\"(max-width: 344px) 100vw, 344px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3><strong>Flexible portable neon<\/strong><\/h3>\n\n\n\n<p><a href=\"https:\/\/substack.com\/redirect\/d3b73e46-5535-4008-ae19-3fda95e674cd?j=eyJ1IjoiMXhmZzB6In0.4ieSFe4rvvESx3-YSOApdZUV-VKuM1Arc6QBuHWifaY\" target=\"_blank\" rel=\"noreferrer noopener\">El Wire<\/a><\/p>\n\n\n\n<p>Do-it-yourself neon. This thin electro-luminescent wire (el-wire) glows very brightly. You can bend it easily, tie it to anything. It produces essentially no heat. Best all of it runs on batteries, meaning you can wear it or use it on your bicycle. We make signs with it and, of course, some wild costumes. El-wire (also called Live Wire) has been used to great effect in the night parades at Burning Man; I still have vivid memories of an animated neon kangaroo (mounted on the side of a bike) galloping across the desert. It comes in various lengths from .5 m to 10 m (you can cut it if you know what you are doing) and in eight colors. You can also make it strobe. It is the world\u2019s most flexible light. It is very cool stuff. \u2014&nbsp;<em>KK<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/kk.org\/cooltools\/files\/2026\/07\/Glow-Tubes-in-bulk-1-1024x1024.jpg\" alt=\"\" class=\"wp-image-46427\" width=\"344\" height=\"344\" srcset=\"https:\/\/kk.org\/cooltools\/files\/2026\/07\/Glow-Tubes-in-bulk-1.jpg 1024w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/Glow-Tubes-in-bulk-1-300x300.jpg 300w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/Glow-Tubes-in-bulk-1-150x150.jpg 150w, https:\/\/kk.org\/cooltools\/files\/2026\/07\/Glow-Tubes-in-bulk-1-768x768.jpg 768w\" sizes=\"(max-width: 344px) 100vw, 344px\" \/><\/figure>\n\n\n\n<h3><strong>Cool bendable lights<\/strong><\/h3>\n\n\n\n<p><a href=\"https:\/\/substack.com\/redirect\/56b18587-69e9-4cfa-83a5-f508ee72c45a?j=eyJ1IjoiMXhmZzB6In0.4ieSFe4rvvESx3-YSOApdZUV-VKuM1Arc6QBuHWifaY\" target=\"_blank\" rel=\"noreferrer noopener\">Glow Tubes, in bulk<\/a><\/p>\n\n\n\n<p>I\u2019m partial to those foot-long noodles that glow in various shades of color, also popular at raves. They are plastic tubes with a glass insert that start to luminesce when snapped. Like road safety sticks but thinner, longer, more flexible and cheaper. These floppy light wands say: be creative! The tubes come with a plastic coupler that can connect them in a chain or in a circle. Since they are flexible and light and cheap they can be woven into bike spokes, sewn on clothes, spun, pinned, or swung. They\u2019ll last 7 or 8 hours and if by chance you are near a freezer you can freeze \u201cignited\u201d ones; just thaw them out and they start glowing again. You don\u2019t have to go to raves or Burning Man to enjoy them. We break them out for Halloween, Fourth of July, birthday parties, and dark nights while camping. Called glow sticks, they are available from a number of online sources (check for rave suppliers). The come in all sizes from mini-sticks to swords.<\/p>\n\n\n\n<p>One or two tubes are okay; the key to the fun is to get them in bulk, by the hundreds. One hundred 8\u2033 sections should be about 10 cents a piece, or $10. One hundred is not too many. It\u2019s barely enough to cover a jacket with them, or decorate 3 bicycles, or make a huge glowing hula hoop, or enough bangles for all the arms at a party. The supplier below has the lowest prices I\u2019ve come across and I\u2019ve used them with no problems. \u2014&nbsp;<em>KK<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<p>Once a week we\u2019ll send out a page from Cool Tools: A Catalog of Possibilities.
