10Pack 3/4″ (19mm) Fire Starter Survival Whistle Buckle Flint Scraper for Paracord Bracelet Key Lanyard Ourdoor Hiking Camping Backpack Bag Pets Collar DIY Travel Kits

These are excellent. I bought them to make paracord bracelets that had a fire-starter. These are nice since they have both components of the starter embedded in one convenient piece.The buckle itself is roughly the length of a wrist though the loops where the paracord go through are positioned in such a way that the cord fits tightly around the wrist. That being said the slots are somewhat tight for 9 strand cord.The pieces as a whole had no obvious defects. All components work as expected. The whistle blew loud relative to other traditional whistles. The buckle works like all buckles. But most importantly the fire starter works well, after the outer coating is scraped off of course. I am by no means a professional when it comes to striking a fire, I’ve only done it twice in my life, but I was able to get a spark at least 1/5 strikes and as well as 1/2 when the striker was positioned well. However I have not actually started a fire with it, but the sparks do seem large enough to be viable a majority of the time.Update: After initially playing around with the starter it became more difficult to get sparks. I became frustrated and started striking it with the edge of a scissors which produced fantastic sparks nearly every strike. I then flipped the striker from the bucked so that the other edge was more available on one side of the buckle. I again received fantastic results with sparks at least 50% strikes having a spark and was able to start a small piece of dryer lint on fire.
