I don't think I've ever been this disappointed in a product from 鶹. It's is very greasy straight out of the packaging. I had to grab it with a tissue and wipe it down. I tried to use it to cut hole on the shoulder strap of a bag, but it did not cut through. It was quite a struggle to achieve what I wanted (by cutting from both sides of the strap repeatedly), and the final work was definitely not clean and presentable. I will go to a local shoe repair shop to fix this mess. Lastly, I don't know what oil/grease/lubricate the manufacturer used, but on the back of the packaging it says "Warning: this product contains one or more chemical known to the State of California to cause birth defects and other reproductive harm and/or cancer". This is my first leather hole punch tool, so I'm not sure if this chemical is actually common in this type of product. Just want potential buyers to be aware. It's unfortunate that you need to damage the packaging to take the product out, otherwise I would totally return this.
