B.I.S.T. or Best Italian Spinning Tools made their debut in 2009 but quickly disappeared from the yo-yo scene a few years later. Today, they are primarily remembered for having created prototypes of yo-yos with unusual designs. That is, designs that were never put into production or sold publicly, such as the smallest metal ball bearing yo-yo in the world—at the time—in 2011. Many of their unique yo-yos were nothing more than personal pet projects of the owner, with the Stradivari being the exception.

(On a side note, the current record for the smallest production ball bearing yo-yo in the world is the Sturm Panzer Secret Prototype at 10.97 mm diameter.)

B.I.S.T. was also known for making modifications to existing yo-yos. A few of the yo-yos they are known to have "modded" include the following:

• B.I.S.T. Centauro
• Duncan Avenger
• Duncan Butterfly
• Duncan Freehand Zero
• Duncan Imperial
• YoYoFactory F.A.S.T. 201 (aka Bandai Mercury)
• YoYoJam Kickside
• YoYoJam Lyn Fury
• YoYoJam Speedmaker

At the World Mod Design Contest 2009, Yuumi Shiga of Japan placed first with his acrylic yo-yo entry One Drop for 363 points. It was awarded best overall. Ettore Ferro of Italy placed second with his entry Stradivari for 361 points. It was awarded best mod.

The number of Stardivari produced is not known. Based solely on owner messages I have read on the Internet and on image searches, a guess would be less than 15. I have seen this yo-yo in a chrome finish (known as the Stradivari Super Ghost), a blasted finish, and with orange anodizing. Other variations and colors may also exist.

According to Ettore Ferro, the Stradivari yo-yo was composed of 30 individual pieces.

Despite Ettore's unique design, the B.I.S.T. website from March 2010 gave only minimal information about the design and making of the Stradivari:

"Stradivari: The making of it was keeping her warm for this occasion, I thought, how better to start than with a review of the Stradivari?
So here I am, let's get started!
The Stradivari is not a real yo-yo in the traditional sense, but a mod, or modification of an existing real yo-yo. The starting point for the Stradivari was—as hard as this may be to believe—the B.I.S.T. Pegasus or PEG.

I chose the PEG yo-yo for several reasons, how do you say? Not interested in hearing them? Never mind .... so as not to harm anyone ... I do as I please (quoted by Ettore Petrolini). We said I chose the PEG because it was my first yo-yo you work (well yes I'm nostalgic) and also because it lent itself very well to being modded.

The wall on the inside, around the bearing, lent itself very well to being drilled, if it had had a more rounded shape it would have been very difficult to drill without the aforementioned holes affecting the game. The straight part of the shape was then indicated to make those slots in ways notches on the violin.

In short, the base for the yo-yo was there. The weight of the stock PEG yo-yo was 70 grams, which guaranteed me that it would be an excellent starting point to be able to work without the fear of dropping too much with the weight.

After a study phase, which took place mainly in the morning sessions in the bathroom, I put down two calculations to understand how much material to remove from the PEG.

The first process was to remove the wings, creating a completely straight shape: Already this is a done and over mod. The yo-yo in this Stradivari configuration weighs 61 grams (light!). It loses the stability typical of the PEG and is really too light."
