Kumiki mini Sparkle Burr
Locked Sprockets (made by Net Block)
This, and the Sphere, have identical pin-locking mechanisms .
(made by Net Block)
Same as Reiss Games' Equilibrium . Also called Astro by Pussy (manufacturer in Germany) .
The name of this sneaky little item comes from the fractious way the mechanism is constructed . As seen in the next pic, the only thing that is holding the puzzle together are the tiny little tabs on the ends of the pieces .
Once assembled, it will stay together with an extreme minimum of handling - affording a distinguished appearance as an intimidating little display . Once the level of handling is raised just a fraction . . . SURPRIZE ! . . . it'll fall apart at a whisper .

Mirrored Burr (version 1)
Mirrored Burr (version 2 - with bolts)
Since I haven't been able to find a satisfactory adhesive for chemically bonding the two differently colored pieces to each other, I have settled for a mechanical bonding, using tiny bolts - one of the colored pieces having been tapped to substitute as a nut fastener .

Knobby Burr pieces
There are two sets of identical triplets . One set, the mirror image of the other . For those of you who feel like making one, go to this website:
Multi Cross This is someone's version of Pentangle's wooden Squirrel's Cage .
Original design by Ronald Kint-Bruynseels . This is probably a level 7 on the Puzzle Difficulty Index from 1 to 10, in relation to others like it . It takes 11 moves just to remove the first piece .
This unique gem is an awesome 6" cube ! An enormous handfull, to say the least .
If you feel like creating one, you can go here for further info : Clarissa Burr
According to a statement regarding the solution on Ishino Keiichiro's page displaying the puzzle, "There are 170 solutions include apparent. 1 solution is constructable . 11 moves to remove the first piece . "
Kumiki Lantern (medium)
Cross This is someone's version of Mag-Nif's Curious Cross . . . Reiss Games' Torment.
Pagoda Small version of the Japanese Crystal as found on the Web, or Bits & Pieces' The Great Pagoda, or Pentangle's Woodchuck .
Mini burr Unknown origin . . . . from Stewart Coffin's 3 Pairs puzzle .
Not only because this is a very small puzzle, but also because of the slippery plastic edges of the 'pairs' of each of the three sticks, this little simple-looking burr affords an extremely high level of frustrating dexterity in controlling the puzzle during assembly . In fact, I have to cheat by tacking pieces of masking tape to certain areas .
3pc Block . . . from Stewart Coffin .
I have designed several styles from this original . . . here
Mini triangle burr . . . origin unknown .
3pc Stepped Pyramid This first in the series was made over 30+ years ago, and recently sold on E-Bay .
3pc Stepped Pyramid - Deep Slotted .
Not only for aesthetic effects, the deep slots add a next-level touch of confusion for the puzzler . The individual cubes that make up the 3 compound pieces are approximately 3/4" .
The Sacred Four
3pc Stepped Pyramid - V-notched .
The V notches add a gentle aesthetic effect with a minimum of added confusion to the puzzler . The 1" blocks were bought at a local crafts store - the kind of wood was not indicated on the package, but it is a domestic hardwood of some sort .
3pc Stepped Pyramid - Shallow Slotted . Again for aesthetics and confusion .
3pc Stepped Pyramid - with holes .
Again for aesthetics and confusion .

Designed by Frans de Vreugd (Netherlands) . According to the description from Puzzle World , "This puzzle is based on the Six-Board Burr by Junichi Yananose. The dovetails reduce the number of possible moves dramatically. The solution is a unique level six (six moves to remove the first piece)" .
The first 120 copies of the Doveltail burr from Frans de Vreugd were made by Bernhard Schweitzer -- a German puzzle collector/craftsman for more than ten years, with membership in the IPP (International Puzzle Party), a private, informal organization whose main objective is to promote and recognize innovative new designs of mechanical puzzles from around the world -- for his exchange puzzle ( made from Maple + Padauk wood) .
The model pictured above -- copied and fabricated from the original version by anonymous craftsmen -- was purchased from Bits & Pieces online catalog .
PinHole . . . from Stewart Coffin .
So called because the locking mechanism are wooden dowels that set into their complimentary holes .
Sonneveld 3pc 2x2x2 cube . . . . . stained only (with MINWAX Colonial Maple)
. . . . . partially open, and given 4 coats of high-gloss acrylic polyurethane
Notice that, unlike a great many burr puzzles whose pieces slide laterally for disassembly, these pieces twist in unison (like a cordinate-motion puzzle) .
However, in practical terms, each piece has to be moved a 'baby step' at a time until final separation occurs .
. . . . . all 3 pieces are identical .
Sheffield Steel 6BB
This is the first in a series of what I like to call 'tortuous burrs' . This humungous 6-pc specimen measures 7" (if it were in cube form) and weighs about 2 pounds . It is made of North American white pine -- at 8% kiln-dried humidity -- and given a two-toned application of MINWAX stain (combination of Red Oak and Natural), and then several coats of acrylic polyurethane on certain areas that will not be affected during the move shifts .
The man responsible for this wonderfully devilish design is Ronald Kint-Bruynseels, and one can view more of his -- and others' -- amazing high-level burrs here on Ishino Keiichiro's website .
According to a statement regarding the solution on Ishino Keiichiro's page displaying the puzzle, "There are 144 solutions include apparent. 1 solution is constructable . 17 moves to remove the first piece . 14 moves next ." . "
To not become unbearingly overwhelmed with the enormity of the number of shifts involved, I enlisted the aid of one awesome program called Puzzlesolver 3D created by André van Kammen at "http://www.puzzle.cx/" (now defunct) .
According to André, "Puzzlesolver 3D is a program for solving 3D interlocking puzzles. It makes it possible to show the found solutions as an animation which can be viewed from every angle. It supports assembling and disassembling for puzzles which are built up using cubic blocks. For example, it solves most 6 piece burrs by the click of a button. It has an easy to use 3D interface for drawing the puzzle. "

Triplets . . . . . made with LiveCube units
3 identical pieces
Little Paperclips . . . . . from Tom Lensch's version of Oskar van Deventer's original design, which can be seen at Puzzle World
This is a level 3 burr : it takes 3 sliding shifts to release the first piece .
Stain was added to give it an aesthetic
'depth & breadth' ; the notches help to balance the overall geometric aethetics, and to create added confusion to an already partially non-symetrical geometry .
The stain is a 2-part combo of MINWAX red oak and natural, enhancing the 2 major soft grains of the wood .
MINWAX wood wax was applied to all shifting surfaces to help reduce friction to an already snug fit .
As with all my puzzles -- having taken influence from, and giving credit to, the great craftsmen of our time -- I try to cross-grain all pieces to minimize expansion & contraction .
Squarrel . . . . . a Squirrel's Dilemma
Another 'tortuous burr' modeled after Ronald Kint-Bruynseels' original, which can be seen here . According to Ishino Keiichiro's website, "There are 12 solutions include apparent. 1 solution is constructable. 10 moves to remove the first piece. "
You are looking at the first 3 shifts out of 10

No Nukes! . . . . . the Titan Beast
This impressively, intimidating design, the forerunner to the Sheffield Steel 6BB above, is credited to Ronald Kint-Bruynseels, and demands a high degree of respect and awe, even from the most serious of puzzlers . The 'core' pieces are slightly similar to the Sheffield Steel 6BB . To assemble just the 'core' required only eight moves . Once the extensions were added, the number of shifts increased dramatically .
This is by far the most frustrating puzzle I have made, and have put together -- even with the 44 move solution, which was created -- as well as those high-level burrs above -- by PuzzleSolver3D .
The extensions are 10 1/4" by 1 7/16", acquired from 3/4" North American white pine finished 1x4 stock .
Weighing in at 2.02 pounds, it is extremely snug . After inserting the sixth piece, from then on to the finish, it was very difficult shifting the pieces, no matter which ones they were . Hard to get one's fingers in between the extensions to grab hold of the piece's core structure, and use both hands -- applying equal pressure -- to make the shifts .
Not only have I given the extensions a two-tone stain effect with four coats of acrylic polyurethane, but I have also created line cuts for added distinction aesthetics .
. . . . . size comparison
This gives you a great perspective as to the mammoth scale of this gargantuan . . . a size akin to some of Vaclav Obsivac's puzzles from the Czech Republic .
You can view the pieces on Ishino Keiichiro's page .
There is a solution there, but with all due respect, a lot of the pictures are hard to follow: sometimes not knowing how many units of shifting travel (and with how many pieces involved in that move) there are .
However, I have meticulously created a solution page myself, with the aid of PuzzleSolver 3D . You can easily follow each step, as the pieces are all differently colored and numbered, and most of the steps (all enclosed within a frame) have two illustrations: the left one representing the puzzle having been turned in orientation from the last step previous, the right one showing the move .

Bill's Baffling Burr . . . . . a high-level rating of 4.2
A very tough burr which takes four slides to remove the first piece ( the actual removal being the 5th move ) . Another two slides to remove the second piece .

L Board Burr . . . . . a high-level rating of 22.3
L Board Burr is a design from the world famous puzzle designer Frans de Vreugd of The Netherlands. This puzzle is composed of 6 pieces that feature an "L" shape. 22 shifting moves are required to release the first piece, another 3 shifts for the second piece, and yet another 3 shifts for the third piece. This is an extremely tricky and very difficult burr .

19 copies of this puzzle were crafted by Steve Strickland of Puzzlecraft , for the International Puzzle Design Competition in Chicago earlier this year. These were made with Maple, Bubinga and Brown Ebony. The plates are 3/8" thick and the assembled puzzle is 2.5" wide. This puzzle is one of these first edition copies.
