Thankfully Just What I Needed!

I used the BigBlue 5T blade for dismantling a collapsed roof over my deck. It worked like a charm and I had that roof in stacked up pieces in much less time than I imagined I could. It made an easy job out of what I thought would be a time consuming pain in the but. Very Happy!

Good choice for roofing demo

Blades worked great

Big Blue Saw Blade

I’ve only used it a couple of times so far, but I’ll be giving it a work out on my roof in the near future. Cuts great and smooth. I’m glad I got it.

The best demo blade I have used

I have been in the carpentry / reno business for over 30 years and I am a hands on working owner. I will say this is the best demo blade I have used. Thanks for a good blade.


Needed the blades quickly so paid for the expedited delivery. Delivered in 9 days vice 2-3

David, we apologize that you did not receive your package in a timely manor. We have refunded the cost of shipping on your order. You should see the refund on the same card you used to make the order within 5-10 business days. This is a problem we have had with USPS recently. They promise quick delivery, but they do not follow through. When we talked to them about it the post office told us that missing shipping deadlines happens with some addresses. This is not acceptable to us so we have decided to use Fedex for expedited shipping to Canada moving forward.
