This ultra-slim knife is 4-1/2-Inch long OA, with a flat metal handle that comes in assorted colors (our choice). The short, broad blade is honed to fit into the slit in a watch case and pop the back off easily. It doesn't fold into itself, but does come in a protective vinyl sleeve for storage. Very sharp. Review: USEFUL FOR FAR MORE THAN JUST OPENING WATCHES - I bought mine when I saw one being used by a profession cell phone repair shop. In certain situations it is the ideal "Spudger". One of those tools that you'll reach for more than you think on your bench. DURABLE as hell! I BROKE the point off one. See pic. BUT what it took to do that was bending in back and forth prying probably SEVENTY times, no kidding! I was impressed. (I bought 2 more to replace it) Its made of 440 steel and it holds a substantially sharp edge too. I hone mine on a diamond whetstone. Slices paper. sharp enough to cut you good. GREAT for EMO'S ;-) You COULD take the sharp edge down some by sanding if you wanted, making it less like a micro katana. IN MY OPINION, this is a excellent quality tool who's uses you will find go well beyond just opening watch backs. If it were sitting on your bench, and no-one told you what it is for, how many uses would YOU find for it? Me? Here's a few: fingernail cleaner, label adhesive remover. De-burr aluminum, Prybar for plastic plugs on aluminum square tube, removing plastic housings from electronic devices, Oh, and I did pry a watch back apart with it too. ;-) Review: Wonderful product - I tried different tools to open the back of some old watches to replace the battery myself without much luck. I saw this type of knife reading some articles on the internet. So I purchased this 4Pk and they really work great. When you hold them you know what a good product you have. Each knife is inside of a sleeve but a second clear sleeve covers the blade; very nice. I did practice taking the back off of some old watches before trying on a nicer watch. I had to look for the lip around the back of the watch using a magnifying glass to place the blade. If you don't have much strength in your hands you can use just the very tip of the blade like I did. The back of the watch came off easily. The number on each battery was easy to replace. With a little W-D 40 on a Q tip applied around the case it snapped back in place. You will save yourself some time and money when you replace the battery yourself and this product will help. ## Features - Length: 4.5” - Stainless steel - Precise sharp edge - Handle comes in black, blue, silver or orange (no color choice) - Great for professional watch repairers, watchmakers, and everyday users to open watch cases ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0001CULSS | | Best Sellers Rank | #812,153 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #1,106 in Watch Repair Tools & Kits | | Customer Reviews | 4.1 4.1 out of 5 stars (889) | | Date First Available | March 13, 2009 | | Department | womens | | Item model number | HN7 | | Manufacturer | Sona Enterprises | | Product Dimensions | 5.1 x 1 x 0.2 inches; 0.71 ounces | ## Images ![SE Watch Case Back Opener - HN7 - Image 1](https://m.media-amazon.com/images/I/71dEuEZuoiL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ USEFUL FOR FAR MORE THAN JUST OPENING WATCHES *by W***S on December 18, 2017* I bought mine when I saw one being used by a profession cell phone repair shop.

Get a stone and sharpen it to your likening. *by G***O on January 24, 2017* This is a pretty good little utility blade. Great for those small jobs for which you don't want to risk your good pocket knife: prying, chiseling, punching holes. And for those complaining that it's too thick or not sharp enough: it has to be thick to withstand prying, and every knife gets dull and has to be sharpened. I've taken away one star because the handle could be heftier, with softened edges, to be more comfortable. Still great for the price. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/2065111-se-watch-case-back-opener-hn7](https://www.desertcart.ae/products/2065111-se-watch-case-back-opener-hn7) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-08-27*
