Has anybody tried or used the Martellato guitar? Here is the link:
Its description says the the shortness of the wire ensures more machanical resistance and the possibility to cut hard and frozen products, which seems to make sense. And the cutting frame always keep at an open angle, contrary to the traditional guitar, which angle closes as it cuts the slab, becoming harder as the resistance increases. Unfortunately, the price tag is very high at US$4,939.00 on the Martellato USA website:
You can also watch a video on youtube:
What do you think? Any input or feedback would be appreciated.
Haven't tried this but Chocolate World has something similar in automatic or manual.
I have a regular Martellano guitar and the strings are really hard to replace.
How is the built of your Martellato guitar?
Pavoni has manual and automatic models.

Do you think the driving-force system is worth paying more money?
It seems like this type of guitar doesn't have the broken-string problems (or not as often) that traditional ones have, which are a pain to replace.
I saw a handmade version of a guitar like this in Bolivia made using - believe it or not - real guitar tuning pegs to stretch the wires. Very ingenious. The main difference is that the material was pushed through the guitar by hand.
The board was shaped like an "L" and material was pushed through one set of strings than pushed through the other without having to be removed from the board. It was made from wood, but no reason it couldn't be made from aluminum and HDPE pretty inexpensively.
I will look to see if I can find the pictures and post.
Thanks for your reply. Do you think this type of guitar would make cutting firm slabs easier and also the broken wire problems would be reduced considerably?
I certainly know that it made it very easy to replace the strings! Also, the strings were short so they didn't stretch very much, making them last longer.
Using the device was a little tricky as it relied on physical strength to push the slab through the strings (with a pusher). At some point, it becomes very difficult to work this way. I can imagine creating a simple ratchet mechanism that would enable someone to apply a lot of force with a little leverage.
I think the same. Because the strings are short, they don't stretch very much, making them last longer. And changing the strings should also be easier.
The guitars shown in the links have a wheel mechanism that, as you said, should enable someone apply lot of force with a little leverage.
