Abbot & Ashby every time if you want quality that works and lasts.
Exactly what I was looking for. A company in the states use an almost identical knife under a different brand name, minor differences, nothing impactful. This has been the knife I have used for work for 10+ years. I keep 2 on hand in case something happens to my daily use one. I will gladly pay the exchange and shipping cost to keep using what works so well for me.
Excellent product Excellent price just needed to wait a little longer for them to arrive, but that's no problem really.
The ordering and delivery process was very straightforward, very happy with the products I ordered. Great service from Beyond Tools, I will use them again.
I have been chasing additional bobbins for years. The original seller did not offer additional spindles.
Beyond tools is able to supply additional spindles. Great
We purchased from beyond tools as we were struggling to locate some brass items in the UK and Europe, we got a great prompt service.
Great service and range of products
The mini hinges are good quality and the service was prompt considering we are in the United Kingdom.
