CAUTION.
As there are so many different kinds of Emery Oil Stones in the market, and many of them worthless, we urge users against buying anything that purports to be a first-class stone unless it bears the names "Whelden Oil Stone" and " Chas. A. Strelinger & Co."

EMERY WHEELS versus GRIND STONES.

Under the above heading the Leland & Faulconer Mfg. Co., prominent makers of grinding machinery, print the following as part of the results of a series of very careful tests made by them as to the comparative value of Grindstones and Emery Wheels
GRINDSTONES.
The stones used were soft and free-cutting, and the very best we could obtain.
EMERY WHEELS.
The emery wheels used were regular stock wheels. The material ground was in all cases Tool Steel, The pressure, speed, water supply and all other conditions precisely alike in all the tests. It will be noticed that the Emery Wheel removed thirty-six times as much stock as the Grindstone, both running the same length of time, which shows a saving of f or 97 per cent in time ; 97 out of a possible hundred is pretty good.

The Leland & Faulconer Mfg. Co., in concluding the article put this query, "Can you afford to grind your Tools on Grindstones?", and we, in concluding this article on Oil Stones, might also say, " Can you afford to Sharpen and Whet your Tools on anything but the WHELDEN EMERY OIL STONE?

SPECIAL SIZES.
We can, when desired, furnish to order, any size in these Emery stones, but only in quantities ; can also furnish stones of coarser grit.
COARSE OR FINE.
When desired we can furnish any of the sizes in table, composed wholly of either the coarse or fine emery ; prices are the same.

Editors note: Emery & grindstones were a very big item in this old catalog, but obviously a lot of things have changed since 1897.  Listed below are Ebay auctions for these items, but there are very few of them.  Obviously we have better ways of sharpening tools these days.  The original text continues after the Ebay ads.


CONSERVATIVE ENGLAND.
Mr. Robert Kelly, Too1 Maker and Cutler, and the largest dealer in Tools in Liverpool, England, had a dozen samples of these Emery Stones. These were sent him to be distributed among a few of the best mechanics, together with a request that their unbiased opinions be obtained. We have the following letter :
LIVERPOOL, Dec. 2d, 1896.
Messrs. CHAS. A. STRELINGER & Co.
Detroit, Mich., U. S. A. Dear Sirs:— Respecting the Emery Oil Stones which we have distributed amongst reliable workmen, we may tell you that we have had three written reports and the remainder verbal. The written ones, which I enclose, speak for themselves, and the verbal reports ran in the same strain. I must now add my own testimony, and tell you that—after the most severe trials—they are the best thing ever placed on a workman's bench. I believe they are destined to take the place of the Washita and Turkey stones. As soon as you are ready to deliver, you can send us 300 of the No. 10 size.
Yours Resp'y,
ROBT. KELLY.
The following are extracts from the letters sent us :
"I find it combines two most essential qualities in one— that is— quick- cutting, and at the same time putting on a keen and clean-cutting edge, which qualities are impossible to be found in any other stone." "It is the best I ever had, and is far superior to the Turkey or Washita stones. The stone is a perfect surprise to me."

ARKANSAS, WASHITA AND TURKEY OIL STONES.

These stones are termed "Oil Stones" for the reason, that oil must be used to float off the particles of steel cut from the tools, and thus prevent them from filling up the minute pores of the stone.

WASHITA OIL STONE.

Washita Oil Stone is found in the spurs of the Ozark Mountains, of Arkansas, near the Hot Springs. It was first put upon the market nearly fifty years ago, and was first named "Quachita" ( since corrupted to Washita) It is composed of pure silica, and its sharpening qualities are due to the small, sharp pointed grains, or crystals, which are hexagonal in shape and harder than steel.
There are various grades of Washita rock. The best whet-stones are very porous and uniform in texture. The poor grades are less porous, making them vitreous, or "glassy," or they may have hard spots or sand holes.

ARKANSAS OIL STONE.

Arkansas Oil Stone is the best sharpening stone known, for engravers, watch-makers, surgeons, and others who use very fine edge tools. It is expensive to manufacture, being nearly sixteen times as hard as common marble. A good Arkansas Stone will, with careful use, last a life-time.
SOFT ARKANSAS OIL STONE
This is a grade between the regular Arkansas and the Washita stone; is especially adapted for sharpening the tools of wood carvers, pattern makers and workers in hard wood; has been on the market only a few years, and has met with a constantly increasing sale.
TURKEY OIL STONE.
This stone is a great favorite with many mechanics. It cuts a little faster than the Washita, and leaves a finer and better edge It is not a very strong stone —this being its main defect. We have them in two sizes: No. 1, 6 in. long, 2 in. wide, and 1 in. thick, price, $0.75 ; No. 2, 8 in. long, 2 in. wide and 1 in. thick, price, $1.00.
QUALITY.
We mean to send out nothing but the best and finest grades of Oil Stones. We pay the highest prices and all stones are selected.
