Handle maker

I absolutely love my new diamond core handle making tool. Making handles has never been easier, I look forward to purchasing more of your tools.
P.S. appreciated the fast delivery.

Love my Koala extruder

So happy with my first order from Diamond Core tools. Order process smooth with timely delivery. It works like a charm. Lots of handles in minimal time -now everything needs a handle! Traditional, strap handle, etc. lol Gives your handles a great professional appearance. Give it a try. You won’t be disappointed!

Excellent Customer Service

I cannot actually give a product review yet except to say, just by looking at this tool, I can see it is excellent quality. Besides, I have other Diamond Core tools and they are the best quality one can possibly get. But, I do want to give a review of their customer service. This company's tools are expensive because they are the highest quality. When I purchase their tools, I can count on them being excellent quality that will be worth every penny and will last a long time. However, I cannot buy one of their expensive tools carelessly. I recently purchased one of their hand-held extruders online. I made not just one, but two mistakes when I ordered the tool. I ordered the wrong tool and somehow I did not notice that I had chosen the "pick up" option instead of having the tool sent to me. As I said, they are expensive, so I was quite upset with myself. When I realized my mistake, I sent an email asking that they allow me to change my order including having the different item shipped to me. It was a weekend, so I had to wait to see if they even read my email before the order was completed. Well, on Monday, not only did I get an email saying they had fixed my order, I got a phone call to confirm that my wishes were taken care of. This company has an excellent product and they have excellent customer service.
