Purchased the Naniwa 12K water stone and holder very fast and prompt service....Spoke with Brad the day before he answered all my questions great to work with, he was the reason I decided to give Maggard my business because of his willingness to all my questions. I will continue to support this company because of the customer service (witch is missing in so many businesses these days) and fast shipping a plus as well......... Thanks Warren Holmes

Alright folks, I had trouble thinking of an appropriate review, I will put most of what I put on an email to the Maggard mob. TL;DR: bloody top stone, worth every cent, dime or penny or what ever your currencies lowest value is called, I received my stone Friday last week, fair dinkum, it is an absolute ripper mate, I thought I was going to look like a drongo using it, an absolute dipstick but I seemed to have taken to it like a duck to water, it was quite simple a process really, I did perhaps 40 passes each side and about 50 passes on my strop and it was cutting better than when it was out of the box. I couldn't give it a good enough review, I just wouldn't do it justice, so I will sit down to eat my dogs eye with dead horse and get to thinking, or I could possibly just use what I have punched out in this email
