Let me start with Customer service is excellent! Responds promptly to any questions or concerns you may have. They reached out to me to make sure they understood the order I placed and to make sure I understood what I have ordered. Most companies just send what you order whether it's right or wrong. That says a lot about their commitment to the customers and their tools.I've tried several name brand pricking irons and some knock off brands just searching for that one. Then I ran into these beauties! Of course everyone is different and everyone has their own opinion. What might work for one person, might not work for another. But IMHO Sinabroks is the best in the market today! Not only are they beautiful to look at, but they feel great in hand, precise stitch marks, and I love how I can now prick through thicker leather when I'm working on sheaths or any project using 8-10oz leather. I bought my first set and enjoyed using them so much I bought 2 more sets. Sinabroks also offers replacement teeth and a jig to repair any damaged tooth so your tool will always be in great condition for many years. Well worth every penny in my opinion. If you're thinking about purchasing Sinabroks, I highly recommend that you give it a shot. You won't be disappointed! THANK YOU so much Sinabroks team for your excellent customer service and products!
