Very good quality. Review: Nice solid Koga - Wanted this as a door knocker (deliveries) and self defense. The Koga is solid but since it is not metal it is not too heavy. Works well for knocking on doors without hurting your knuckles. Feel a bit safer when delivering to neighborhoods I am not familiar with. ## Features - Innovative Classic Design - High quality build materials for peak performance and durability - Perfect aid to leverage when restraining an individual - Use for intermediate impact tool - Small yet powerful self-defense tool ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01M67HBHD | | Item Dimensions LxWxH | 10.2 x 2.5 x 27.9 Centimeters | | Item Weight | 136 g | | Item model number | VK-9350+91K | | Manufacturer | Cold Steel | | Product Dimensions | 10.16 x 2.54 x 27.94 cm; 136.08 g | ## Images ![Cold Steel Koga SD1 Made of High Impact Polymer - Good for Self Defense, Security and Sports. - Image 1](https://m.media-amazon.com/images/I/41NvEtb71LL.jpg) ![Cold Steel Koga SD1 Made of High Impact Polymer - Good for Self Defense, Security and Sports. - Image 2](https://m.media-amazon.com/images/I/51GZ+w6gjKL.jpg) ![Cold Steel Koga SD1 Made of High Impact Polymer - Good for Self Defense, Security and Sports. - Image 3](https://m.media-amazon.com/images/I/51IL3Wf9BXL.jpg) ![Cold Steel Koga SD1 Made of High Impact Polymer - Good for Self Defense, Security and Sports. - Image 4](https://m.media-amazon.com/images/I/51btmBtWzfL.jpg) ![Cold Steel Koga SD1 Made of High Impact Polymer - Good for Self Defense, Security and Sports. - Image 5](https://m.media-amazon.com/images/I/51gTqRYhNcL.jpg) ## Questions & Answers **Q: what are the dimensions of this item** A: The Overall Length is: 7-1/2 Inches.

Very good quality. ### ⭐⭐⭐⭐⭐ Nice solid Koga *by S***R on 1 November 2025* Wanted this as a door knocker (deliveries) and self defense. The Koga is solid but since it is not metal it is not too heavy. Works well for knocking on doors without hurting your knuckles. Feel a bit safer when delivering to neighborhoods I am not familiar with. ### ⭐⭐⭐⭐ A Modesty Blaise's fan dream come true (but it should have been smaller) *by K***D on 4 June 2026* Being a fan of the British Modesty Blaise comic strips, I was happy buying all those yawara sticks for my own personal reasons. My only complaint is that it wasn't a more compact, dumbbell-shaped yawara stick like Modesty Blaise's kongo. (I can't actually hide it in my hair or hide it on a purse being male) ^_^() ## Frequently Bought Together - Koga SD1 Made of High Impact Polymer - Good for Self Defense, Security and Sports. - guanma 6.5" Cold Steel Koga SD1 Self Defence Tool Made of High Impact Polymer Good for Self Defense Security Sports - Big Rig Defense: Hickory Stick Tire Thumper - Fish Bat Self Defense Bat - Truckers Tool for Checking Tire Pressure - Weighted Baton with Extra Grip --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/724156704-cold-steel-koga-sd1-made-of-high-impact-polymer-good](https://www.desertcart.jp/products/724156704-cold-steel-koga-sd1-made-of-high-impact-polymer-good) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-18*
