Griffin Magic Mini Jacks

7 Reviews


The Magic Mini Jacks can be used to ream open the smallest opening using on of the triangle shapes blades and moving in and out of the flame. Use the outward force of the beveled edge jack blades for opening any 2" or smaller tube or encalmo section for a nice even wall and cup shape. Other great uses for the Mini Jacks are finishing of hollow beads, pendant loops, fine tuning a mouth piece or raised carbs or even opening the constriction on a down stem. The Mini Jacks are made of hardened stainless steel which can withstand much more heat than common stainless steel. The jacks can be held directly in the flame for a few seconds without damage to the steel. Although the ideal use of the jacks, the glass is in between the tool and the flame and in many case the shaping is done just outside the flame. The dimensions of this amazing tool are 8.5" long and the blades are 0.5 mm wide at the tip going up to 0.35 mm at the widest edge. The flare dimension range is from 1 mm to 55 mm.

Love These!

A little smaller than i expected but they work great. Very versatile tool. Nice tension for flaring.

Incredibly Useful

They are for sure smaller then I expected for some reason but if you're a beginner these are perfect to learn how to use jacks. They work very well for flare small pieces and pendant loops. Keep them waxed or they'll rust.

Good but Price

I always have these on my desk I use them whenever working hollow, however I feel the price is a bit high for what they are. They flare medium to small tubes well and can open the tiniest of holes. Make sure to wax them

I've owned these for about 3 years now and I use em for everything from flaring open the tiniest holes to forming perfect female fittings. way better than a normal octagonal reamer and it will last a lifetime. definitely a must have!!

I love these Jacks. Perfect, fit for my hands and love the way they perform. They are sharp. They are heavier then I anticipated and great tension. Would recommend these. Great tool for the reasonable price. Fast delivery on top of it.

Quality but ?

Great tool but they dont use stainless for the whole tool, everything that touchs glass is stainless but the roller that keeps them spread they made out of regular steel so it started to surface rust in a week and for the price common...

You should have this tool on your bench


I was skeptical at first but as soon as I use them to flare my glass on glass joints I knew they were keepers I always have them on my bench. They hold up extremely well and you can get into a small hole better than a Tungsten pick and some cases.
