Stag would be perfect. I would also like to see the cross-cut saw shield.

[Earl]

Hmmm...... definitely different on the spiral buff,prefer it run up to bolster

Some primo stag would be sweet. That CM version sure works for me,great look and with the non stamped shield,really sets it apart from the others jmho.

very nice Jim one of favorite materials ...

My Lumberjack arrived earlier today. Here is a quick review/first impressions... This certainly is a massive knife but I kinda thought it would be bigger still Smiley. Holding the knife with the spear open is very comfortable and the blade is one of the sharpest I've gotten from GEC. The micarta has a nice feel to it, not too polished. I can't say it is as comfortable with the saw open as the spear blade does stick out a bit. Perhaps it would feel better with work gloves on? And if I file down the kick a bit? I didn't get a chance to use the saw, not sure I have any wood to use it on either. I also took some quick comparison pics with a #25 and a #73 I had out.

Very nice Trand, It appears to be a beast... I have one comming. BH

[paulsvintage]

Monk & Trand good luck with them !

[paulsvintage]

well i needed a single blade one............only you guys would understand............

[Gunstock Jack]

I know exactly what you mean Paul! Once you handle one of these knives, you've gotta have one! I'm a big fan of the single blade too! Nice pick-up.

[Earl]

Trand,great comparison pics ,thanks

Paul, of course we understand ,nice proto and great pic.

Barry is that a Dusk BH...looks nice

[Gunstock Jack]

Barry is that a Dusk BH...looks nice [/quote]

Thanks Earl. Yes it is dusk buffalo horn and it's a nice one, (and it's in my member store!) I kinda wish I could keep it though!

[IMBand]

GEC posted these pics of the Sawcut Cherry handles for the #45........

IM

[boggs]

I'm with you on these in Cherry Wood..........

[legio]

Nice ! Cherry wood......


Are these single blade or combined with the saw?

Thanks, Edgar

[IMBand]

The Sawcut American Cherry will have the saw.

My pair of Lumberjacks together at last. I had sent the canvas one down to WV for some saw testing (I really wish it performed better ). The lanyard added by Ash/Knife_Crazied (not sure she's a member here though).

[boggs]

Now that's just wrong.......how can GEC do this to us.....Smooth and Sawcut Cherry Lumberjacks

[IMBand]

Nice post boggs!!
I like the idea of American Cherry for handles and they surely did a fine job.

**any chance these pieces of... "Ivory, but what animal?" ...are large enough for a #45??
pic is from GEC's 'What's Happening' section.

[boggs]

The Ivory certainly looks like it could be wide enough to cover a Lumberjack......as far as what animal it comes from.....how about Warthog

[Gunstock Jack]

I personally like the smooth saw shield better than the saw with the embossing, but they are both great looking knives!

I'm fairly sure that the ivory is pre-ban elephant, and some good looking stuff, too! I can't think of any other animal (except mammoth) that would have large enough tusks for slabs that size. Walrus would be large enough, but is illegal to import into the lower 48 although legally sold in Canada. It is also prohibitively expensive.

[paulsvintage]

very nice Jim .

[boggs]

Barry..

I'm with you..the smooth cherry with the plain shield does it for me.................as for the Ivory..I was kidding about the Warthog,way to small......but you're probably right Barry about Elephant though my other thought was Hippo for a change of pace.....


What is Ivory?

Ivory is formed from dentine and constitutes the bulk of the teeth and tusks of animals. The word "ivory" was traditionally applied to the tusks of elephants; the word is ultimately from Ancient Egyptian âb, âbu "elephant". "True" ivory comes from elephants and mammoth; however, the term is generally applied to the tusks of other mammals, and some synthetics. Chemically, ivory is similar to bone and antler, and comprises a collagen matrix with a mineral component. Unlike bone, ivory has no blood vessel system, and is therefore more dense. The most commonly found ivories in North America come from elephant, walrus, sperm whale, and hornbill.

Different Kinds of Ivory

It is possible to tell these ivories apart, as they are structurally different. This category includes ivory from both Indian and African elephants, as well as ivory from mammoths and mastodon. The tusks, or upper incisors, of these animals are used. They can have a cross section of up to 20cm (8"), and be up to 2.5m (almost 3 yards) long. They are oval in cross section, and are made up of a hard, dense tissue called dentin, which is made up of 70% inorganic material, and 30% collagen.

1. Elephant Ivory
Unlike human teeth, elephant tusks do not have an enamel coating. They do have a cementum layer, however; ivory dealers refer to this as the "bark" or the "rind". Occasionally this layer is retained on a piece of worked ivory. One-third to one-half of an elephant tusk is hollow.

Growth occurs as layer upon layer of calcified tissue is deposited on the interior of the tusk; you can see these concentric oval growth lines (called the Lines of Owen) in cross section. If you cut ivory lengthwise, these lines appear triangular. Fine and even near the hollow of the tusk (the pulp cavity), these lines become wavy and have milky areas between them as you get closer to the outside of the tusk.

Unique to elephant ivory are the Lines of Retzius. These fine intersecting lines are visible in cross section, and give an engine-turned effect (intersecting lines with a diamond shape between them).

Elephant Ivory is probably the most commonly used ivory in jewelry, both costume and fine. Its most distinctive feature, if it can be found, is crosshatching. A bangle bracelet will usually show crosshatching on at least two small sections, however, many pieces of elephant ivory will not show any crosshatching because of the angle of cut through the material, though you should be able to find some grain lines. Mammoth ivory is the only other ivory that shows the crosshatching

Generally, elephant ivory has a fine, even grain and is easily carved in all directions. It can be thinly cut (i.e. for piano keys), and can be more delicately carved than bone. This ivory is often painted or stained, dyed, and gilded. When cut, the pores of the ivory fill with an oily substance, which helps the ivory polish up nicely.

2. Hippopotamus Ivory
This is the second most commonly used ivory, after elephant ivory. Often used for flat items, such as buttons and inlays, it comes from the lower canines and incisors of hippos. The size varies, depending on the size of the animal.

The lower canine is curved, and has a triangular cross section; the incisor is straighter, and has a circular cross section. Both have two layers of dentin: an outer, primary dentin, and an inner, secondary dentin. The innermost layer has a marbled appearance which differs by species, and can even appear to have a greenish cast. The pulp cavities of these teeth are fairly small. Unlike elephant ivory, hippo ivory does have a thick enamel coating.

Hippo ivory is denser than elephant ivory, harder to carve, and has a finer grain. There is none of the "engine turned" effect in cross section, rather, hippo ivory has concentric rings in cross section. Finally, hippo ivory is less prone to decay than elephant ivory.

3. Walrus Ivory
This ivory comes from the upper canines of walrus. It is oval in cross section, and can be over 2 feet in length. It has an inner dentin layer (which has a high mineral content; it forms as the tusk grows, and leaves a marbled look on finished objects), an outer dentin layer, and a smooth, dense cementum layer. Walrus ivory is used primarily for small objects.

4. Sperm Whale Ivory
Thirty teeth of the sperm whale can be used for ivory. Each of these teeth, up to 8" long and 3" across, are hollow for the first half of their length. Sperm whale ivory is easily confused with walrus ivory, as both have two distinct layers. The inner layer of sperm whale ivory, however, is much larger. As well, in a longitudinal section, sperm whale dentin has yellow "globules" included in the marbilization.

5. Hornbill Ivory
This comes from the casque or epithema of the Helmeted Hornbill, a bird native to the East Indies. It is distinguished from the rest of its family (the Bucerotidae) by having the front of its almost vertical and slightly convex epithema made of a solid mass of horn. This "horn" or "ivory" is quite hard and closely-textured. This substance is used to make small objects such as buckles and brooches, and is highly valued by the Chinese. In cross section, you can see a bright yellow interior with a scarlet rim.
6. Vegetable Ivory

The source of vegetable ivory is the inner seed of the South American ivory palm, and is thus completely made of cellulose (rather than collagen). These seeds are the size and shape of a small hen's egg, are very hard, and are solid all the way through. Vegetable ivory is smooth, takes a good polish, easily absorbs dyes, and is relatively inexpensive. It is used for small items only, such as dice and buttons. Since about WWII, vegetable ivory has been largely replaced by plastics.

7. Synthetic Ivories
Since 1865, when it was first invented by Alexander Parkes, celluloid has been used as an excellent ivory substitute. Casein has also been used. Names for these "faux ivories" include French Ivory, Ivoride, Genuine French Ivory, Ivorine, etc. Both grain patterns and the engine turned effect are added -- in general, the patterns of these are very regular in the fakes, and more irregular in the real thing. In instances of very good imitations (i.e. using celluloid), chemical tests are required to tell real ivory and the fakes apart.

8. Mammoth Ivory

Elephant and Mammoth ivories are distinguished by a peculiar structure in the grain properly called Schreger lines, and referred to as cross-hatching, engine turned effect, or stacked chevrons. Whether this structure is seen depends upon the direction of cut of the elephant or mammoth ivory. Some ivories have a grain, best described as similar to tree rings in miniature. How, and where they appear on a piece of jewelry, depends upon the angle of the cut.

The Mammoth Ivory is excavated from the permafrost of the Siberian tundra, which the wooly mammoth inhabited for more than 160,000 years. During the last ice age, the mammoth went extinct as the direct result of rapidly plummeting temperatures that literally flash froze the entire population of Mammuthus primigenius. The dry, cold environment of Siberia combined with the massive sheets of ice from the ice age created the ideal environment for the preservation of Mammoth Ivory. The wooly Mammoth have been entombed under the Siberian permafrost ever since, waiting to be unearthed.

For more than 2,000 years, Mammoth Ivory has been traded and it remains a highly prized commodity across the world. While that demand for the Mammoth Ivory has always been higher than its supply, it skyrocketed in 1963 when the CITES agreement was enacted. This agreement banned all sales of new Elephant or Walrus Ivory, in an effort to protect the animals from extinction. As a result, Mammoth Ivory became the only type of animal-based ivory that is exempt from the international trade restrictions because it is considered to be a fossil. Over the past few years, the price of Mammoth Ivory has more than doubled, due largely to the unprecedented demand for luxury goods from such emerging countries as India and China. This trend is expected to continue.

How to Tell Real Ivory from Imitations

Imitations are usually made from resins. Sometimes these resins will be blended with the remnants of ivory or bone carvings ground up to a fine powder. There is also "french ivory", "celluloid", or "ivrine". This type of "man made" material looks like ivory with very nice grain. However, the grain is very wide and consistent (too consistent). This material was used mostly for dresser accessories such as brushes, combs, change boxes, letter openers, page turners, etc. Resin items will not have the weight of ivory. Ivory has a very heavy specific gravity compared to most materials.

Looking for "ivory grain" is not always dependable to tell "real ivory". Some ivories have little grain. There is Western Africa Ivory and Eastern Africa Ivory. The ivory from the eastern side of Africa is referred to as "soft ivory" which is duller and contains more moisture and stands changes in temperature better. The ivory from the western part of Africa is referred to as "hard ivory" which is glassy and translucent. The Japanese used a lot of the western ivory for their okimonos. Elephant ivory does not always have obvious grain. In many cases, ivory graining varies depend on how the ivory was cut and which section of the tusk it comes from. The tusk tip is most valued since large part of the tusk is acutally hollow. The tusk tip is more suitable for carving as it is solid, and the tip usually displays the most beautiful cross-hataching grainings.

Bone has tiny little channels where the blood vessels and nerves resided. You can often see these, either straight in (on the backside) looking like little pockmarks, or as lines at an angle almost perpendicular, ie "dots and dashes". It can be easy to see, but also sometimes is not apparent on the surface, however, if you put a light behind it (lay it on your scanner) you should detect the short little lines of the channels.

Thanks for posting that very informative article on ivory Jim. I didn't know most of the info. Ivory from a bird? Whoda thunk it?
