SST - Drag Knife - ⅜” Hardened Steel Shaft - Cuts Wood Veneer, Plastic, Leather & More - Precision Thumbscrew for Easy Blade Length Adjustment - Compact Body - Collapsible

It's cutting through 10mm corex like butter. The worm drive blade adjustment is an inspired bit of design. I'd buy another if I needed to but SST offers all the replacement parts through their website so I won't ever to do anything but rebuild it!

I purchased this dragknife in Sept. 2022 and here it is March 2023 and I am just getting around to using this. Part of the reason is that I was a bit intimidated to use it. Stupid me. I am using Vectric Pro with the dragknife toolpath gadget. The one thing that confused me was the setting for the blade offset. Not having any experience with this so I reached out to SST on a Sunday morning figuring that I would get a response early in the week. Well, in less than 3 hours I had my answer. GREAT customer service. Thought I would share the answer to blade offset:The offset is adjustable, so you will need to measure it in order to plug in the value to your drawknife software.Both the blade height and offset have a 1:1 ratio with each other, so in order to get the offset value you just need to measure the blade height (from blade tip, to the bottom face of the drag knife)

Updated: Customer service reached out after contacting through Amazon, instead of website. They were extremely helpful on getting the bent shaft replaced. Extremely happy with the product and believe the previous email issue was an anomaly.Used in production of cutting felt for a few months. Noticed circles were not meeting from start to finish point. The 1/4” shaft bent slightly, probably needs to be 1/2”. Reached out to customer service close to 2 months ago and have not heard back.

After owning a few different brands of dragknife, the overriding issue to us is how well it stands up over time. Several have small offsets and details to hold the blade, after a while it gets tough to register and keep it all in place. Not with the SST brand. You can see it hits properly on all those details, such as holding the blade depth, not letting the blade slide, and controlling the offset. This is definitely the best one we have used.

Shaft bent on first go, but still works.

Really well designed and well constructed tool.The depth/offset adjustment is simple and effective

Since I’ve started using a CNC machine I have used a few different drag knives, this by far is the best one yet. I would recommend this product 10/10 times!

I have a couple SST Tools. I found them well built and extremely accurate. This is the kind of attention to detail I need with a industrial CNC. The build quality is above bar and well done as to be expected from them. Easy blade change and repeatable cuts is not just an expectation but a necessity when using a drag knife this tool provides that! I would recommend this to anyone looking for a high quality drag knife.

Es una gran herramienta para tener en tu taller,la navaja se mantiene recta en el corte ,todo lo que especifica el fabricante lo cumple. Estoy contento con mi compra.
