Machete Fighting in Haiti, Cuba, and Colombia
MEMORIAS Revista digital de Historia y Arqueología desde el Caribe colombiano Peinillas y participación popular: Pelea de machetes en Haiti, Cuba y Colombia 1 Peinillas and Popular Participation: Machete fighting in Haiti, Cuba, and Colombia ∗ Dr. T. J. Desch-Obi Recibido: Agosto 27 de 2009 Aceptado: Noviembre 8 de 2009 RESUMEN: Este artículo explora la historia de esgrima con machetes entre los afro- descendientes en Haití, Cuba y Colombia. El machete, como un ícono sagrado de éxito individual y de guerra en África, se convierte para los esclavizados Africanos en una herramienta usada en la explotación de su trabajo. Ellos retuvieron la maestría en esta arma a través de la extensión del arte de pelea con palos. Esta maestría en las armas blancas ayudó a transformar el machete en un importante instrumento en las batallas nacionales de esas tres naciones. Aún en el comienzo del siglo veinte, el arte de esgrima con machetes fue una práctica social muy expandida entre los Afro-Caucanos, que les permitía demostrar su honor individual, como también hacer importantes contribuciones a las batallas nacionales, como la Colombo-Peruana. Aunque la historia publicada de las batallas nacionales realza la importancia de los líderes políticos y militares, los practicantes de estas formas de esgrima perpetuaron importantes contra- memorias que enfatizan el papel de soldados Afros quienes con su maestría con el machete pavimentaron el camino para la victoria nacional. PALABRAS CLAVES: Esgrima, afro-descendientes, machete. ABSTRACT: This article explores the history of fencing with machetes among people of African descent in Haiti, Cuba, and Colombia. The machete, a sacred icon of individual success and warfare in Africa, became for enslaved Africans a tool used in exploiting their labor. -

4 Remembering the War in the Solomons
4 Remembering the War in the Solomons Jonathan Fiji'; The Coming of the War The white people told us that a war would eventually come. But even though we listened, we didn't believe them. We couldn't think of any reason that fighting would come to the Solomons. Other people advised us that if fighting did come, we shouldn't be afraid. They said that even if a bomb fell, it would be five minutes before it exploded. All we had to do was pick it up and throw it to where it would explode away from us! 1 In 1942 I was still at schooi at Kwailabesi, in northeast Malaita. One day we saw the Seventh Day Adventist ship Melanesia arrive. But there were no . Solomon Islanders aboard, only missionaries. They warned all of the students that fighting was coming soon. They said "We will be leaving tonight. We can't say if we will ever see you again. But though we are leaving, the Americans may come to evacuate you. You must not worry, because there are Seventh Day Adventists among the Americans too." Some of the other students and I prepared to see our teachers off. At dusk we boarded a small postal boat, and we and the Melanesia traveled along in the dark, without any lights. By daybreak we had reached Siota, on N ggela, and at Taroaniara we camouflaged the two boats with branches. We went in two dinghies to Tulagi, the capital at that time, to see what was happening there. Very few people remained in town. -

Twice As Sharp® Operators Manual
OPERATORS MANUAL TWICE AS SHARP® Scissors Sharpening System Customer service 1-800-888-3832 Professionally Sharpen Scissors and Shears manufactured by WOLFF INDUSTRIES, Inc. BACKGROUND INFORMATION ON LEE WOLFF Inventor of Twice as Sharp® 1930 - 1996 In 1957 Lee Wolff started a sewing machine sales and service business. Fabrics and a complete line of sewing needs were added in 1963, and the number of employees grew to 25 to handle the volume. During those years, Lee did a great deal of scissors sharpening and repair and made im- portant modifications on the available scissors sharpening equipment. In 1971 Lee and Mary Wolff became the first major importer and distributor of plastic handled scissors in the United States. They started to manufacture sewing scissors in 1973 under the trade name of KNIP. A U.S. patent was granted on the KNIP. The scissors factory was sold to American Scissors Corp. in 1980 and moved to the south. Lee set up the factory and innovated many new manufacturing processes. The July 1983 Consumers Reports rates the American Scissors designed and produced by Lee Wolff as a best buy. He also designed a full line of unique plastic handled scissors with interchangeable parts. Lee worked on perfecting the process of scissors sharpening for many years. It is necessary to accurately control the cutting angles, reduce burr formation during sharpening, and do deburring and micro-sharpening as a final process. This method produces scissors that are normally twice as sharp, hence the name Twice as Sharp® scissors sharpener. A United States patent has been granted as well as several foreign patents. -
An Example from Copper and Bronze Age South-East Iberia
Lithic perspectives on metallurgy: an example from Copper and Bronze Age South-East Iberia Selina Delgado Raack and Roberto Risch Departament de Prehistòria, Universitat Autònoma de Barcelona, Spain To the memory of Volker Pingel Summary. One of the centres of early development of metallurgy is the South-East of the Iberian Peninsula, where it played a key role in the formation of the so called Los Millares and El Argar “cultures” during the 3rd and first half of the 2nd millennium BC. Yet, most arguments about the importance of metalworking are derived from the funerary evidence, i.e. from the finished objects used as grave goods, while direct evidence of the production processes is still scant. During the last years systematic analyses have been carried out in South-East Iberia concerning the (macro-) lithic artefacts coming from a series of Copper and Bronze Age settlements and necropolis. The observation of features and traces related to metalworking on some of these labour instruments has allowed to identify the final stages of metallurgical production, as well as to the maintenance of metal artefacts. The functional analysis of these tools and their spatial distribution at a regional as well as local scale reveals important aspects of the social organisation of the process of metal production. Finally, the different technical situations are evaluated in order to understand the changing relationship between metallurgy and the emergence of new forms of domination and exploitation. Résumé. Un des centres les plus anciens de développement de la métallurgie est le sudest de la péninsule ibérique, où cette technologie a joué un rôle crucial pour la formation des « cultures » de Los Millares et El Argar, pendant le III millénaire et la première moitié du II millénaire BC. -
15 Degree Sharpening Module for Use on Chef’Schoice® Model 2100 Commercial Sharpener
INSTRUCTIONS 15 Degree Sharpening Module for use on Chef’sChoice® Model 2100 Commercial Sharpener Module shown inserted in Model 2100 Sharpener. (Sharpener not included). Read these instructions before use. It is essential that you follow these instructions to achieve optimum results. © 2011 EdgeCraft Corp. INSTRUCTIONS FOR USE OF 15° SHARPENING MODULE EdgeCraft offers the 15° detachable sharpening module designed specially to place a factory quality edge on Japanese, Asian style knives and all other 15° knives. It can be used inter- changeably on the Model 2100 Sharpener with the standard 20° module designed for the European/American style blades and all other 20° knives. The 15° module is identical in size to the 20° module and it can be removed or installed on the guide rails of the Model 2100 as described in the Model 2100 manual. The 15° Japanese/Asian module can be used for either straight edge or serrated edges, how-ever the 20° European/American module is recommended for sharpening serrated blades because serrated blades are predominantly manufactured with 20° edge angles to provide greater support for the individual serrations. While Asian style knives have historically been sharpened at about 15 degrees at the factory and European/American style knives have been made with 20 degree edges, very recently leading German factories have introduced European style knives edged at 15°. Remove the standard 20° European/American module from the 2100 sharpener and install the 15° Japanese/Asian module as described in the Model 2100 Instruction Manual pages 11-12. Understanding THE DIFFERENCE – EUROPEAN/AMERICAN AND Japanese/ASIAN STYLE KNIVES In general you will find that Euro/American blades shown in Figure 1 are sturdier than the more delicate and thinner contemporary Asian blades as illustrated below.
