Testimonials

ACTUAL CUSTOMER TESTIMONIALS sent to us via email or others:

From Ryan:I just bought some mold polishing stones from you guys to use or finish sanding knife blades. I tried them last night and they work excellent. I'm not sure what to use as lubricant. I had 3-1 so I used that and it worked but I can tell it's not optimal and that I should get something lighter.

From Rob: You were right, we love the UTR-70. Please send my new order for a second one and the diamond files ASAP. Thanks Rob.

Or this one? Heinz,I received your tools and they worked great. I used the diamond file to shape the small stone. I'm sure I will be buying more tools from you from time to time. Your Website   is great, very easy to use. Thanks for your help, Franklin

Hi, I just wanted to pass on my compliments on the way your company handled my first order. Great emails and even a follow up phone call with a real person! This will not be my last order with your company, rest assured. Respectfully, Ken Erick..........

Hello, I received the stones the other day, good work! I unpacked and used the stones   for the first time today, and I am very impressed with their quality. Thanks for your quality tools and service! regards, Joe 

Here is one we enjoyed receiving from a valued Canadian Customers in BC: Hi  there! My order arrived here on Christmas eve. I am so very pleased and grateful. Wishing you and your team a terrific New Year! Cheers, Patricia  

We purchased some grinders and UTR-70 UltraLaps recently and have been in the business for many years, (I am old), and I am very impressed with the quality of all the items purchased, with the low cost being an added bonus. I also purchased some ceramic stones which are very impressive. Thanks to you and your team. I will be passing your company info to other tool/die makers promoting your products, good job. Sincerely Lee Fry, Tooling Specialist

One Customer responded after purchasing a G5 unit: :"Everything is working perfectly; please let Heinz know. I would like to order spare collets for the unit."

From a Customer in South Africa: Just to let you know, I have started using the stones I bought from you on SS knife blades, hardness about 62, and I am very satisfied with the results obtained. It is now a pleasure to sand those blades using your stones! Kind Regards, Danie

Here is one from an expert Gunsmith: Thanks! I got the package and used the new files to fit a 1911 barrel. They worked really well and are much more affordable than standard gunsmith files elsewhere.

From one of our good customers in Washington State: We haven't had a lot of molds coming through lately, but my ceramic stones were low. I use a lot of them along with the Boride Stones. Thanks for your awesome customer service. Have a good summer, Connie.
