"Certainly not required, but made trimming small pouches so much quicker and easier. Super sharp right out of the box."
"Absolutely loves these corner knives!! Have them in all sizes--use the 25mm the most. makes corners look smooth and clean. A wonderful find."
"This is, hands down, my new favorite tool. Not only does it cut into leather like butter, you can tell the quality as a whole is there. I have struggled with corners since the beginning, but this knife instantly solved that issue. I wish I would have bought one a long time ago. It came razor sharp out of the packaging, and I feel like it will stay that way for a long time. This tool isn't a punch, you simply put a little pressure down and it slices right through. I tested with 2oz all the way up to 10oz and had no issues at all getting a perfect cut with ease. Chucks videos are the first place I go to learn something new, and if this knife is any indication, Weaver is also the first place I will go to shop from now on. Well done, Weaver leather!"
"Works good"
"I love it, it’s very sharp, easy to use and makes much cleaner corners."
"These are some of the best tools that Weaver offers. They are incredibly sharp and incredibly precise. No maul or hammer needed, just push the tool and it will slice right through the leather. They are pricey for sure, but such a great tool."
"The blades on these Kadomaru corner knives are sharp. The smooth corners they give me on projects really adds a finished professional look. For sizes so far I have the 15mm and the 25mm knives and I will continue the collection."
"Excellent corners when using. Extremely sharp"
"Love this thing! Makes the sweetest round corners. Super easy to use and get a good result."
"Quality tools that are well designed and constructed making them easy to sharpen for years of use. So sharp when they arrived I can cut corners with just a little hand pressure, no mallet needed. Delivery was very quick after order placed."
