Concrete Edgers and Groovers

Concrete edgers and groovers have been made by more companies in the USA than have made brick trowels. This is probably a result of the manufacturing differences between them. Casting iron and bronze is less demanding than forging and tempering high carbon steel. Old edgers and groovers are more likely to survive than old trowels, and they are also much easier to identify because the maker’s name and city are almost always cast into the top.

   

A concrete edger is also called a sidewalk edger and hand edger. The concrete groover is also called a hand groover and concrete jointer. They have been made from cast iron, brass, bronze, zinc, stainless steel, and steel, with wood or plastic handles. Specialized edgers have been made for building industrial and farm structures, such as dairies.   

All major US trowel manufacturers make edgers and groovers. Here is a list of other US makers and brands over the past 100 years, with their locations where known:

Collecting Mason's Line Pins

Promotional line pins are a specialized branch of masonry tool collecting. Because of the advertising stamped on them, dating them is easier than with other tools. They promoted cement, mortar, and brick manufacturers and suppliers and occasionally other businesses.

Why Collect Trowels?

The trowel is one of mankind's oldest tools. Its invention by people around the globe is a marker for a civilized society that worked metal and built with masonry. The first trowels were probably of wood, then bronze, iron, and finally steel. While other construction hand tools like the hammer and saw have been partly replaced by power tools, the trowel has not. The simple shape of centuries ago remains the best tool for the job today.

This continuity of design is one of the challenges of collecting trowels. Dating them is near impossible, and there are no written guides available. However, this should not interfere with the satisfaction of collecting a tool with such a long history.

A Nearly Forgotten Tool, the Indent Roller

The indent roller is used to add a waffle texture to troweled concrete, usually curbing or entire sidewalks. The purpose is to create a more slip resistant surface. It's also called an indentation roller, dot roller, imprint roller, curbing roller, spiked roller, and pavement roller. The cylinder may be cast aluminum, brass, bronze, or iron.

How To Clean a Used Trowel

First, if your trowel is very old or unique, please do not do more than clean the dust off. For all other trowels, read on.

The average used trowel bought for $3 at a flea market will be encrusted with mortar, concrete, tar, or all three. It will need heavy duty cleaning to bring it to usable condition. See the list of supplies below.

Start by protecting the handle with a coat of paste wax, which is easily removed later. Place the trowel on a board or other sturdy outdoor work surface. Flood the blade with water and attack the mortar with the scraper. Work with the grain of the blade, which was ground diagonally parallel with the 2 sides of the tang. This will help minimize scratches in the steel. Continue washing the blade with water as you go.

After removing as much as possible with the scraper, switch to the stone and use it like a sanding block. The grit in the stone is harder than the mortar, and does a good job of abrading it. Take care to concentrate on the mortar, avoid too much wear on the steel. and use lots of water. Use the scraper again where needed, like on the tang.

Turn the trowel over and repeat the cleaning on the bottom. Here the grain runs straight from toe (tip) to heel.

Last, use the 400 grit paper for spot sanding and a final all-over cleaning. Dry the trowel very well. If the handle needs sanding or scraping, wait until the wood is completely dry. Last, protect your work with an all-over coat of paste wax.              

You will need:
Outdoor work space
Paste wax (the yellow stuff in a can)
Carborundum or equivalent rectangular sharpening stone
Steel scraper with a beveled edge (mine is a 1.25 inch Hyde with black nylon handle)
Automotive grade 400 grit sandpaper
Water resistant sanding block
Bucket of water
Shop towels

History of Nicholls Manufacturing Co., Ottumwa, Iowa

In 2013 I bought 8 unused plaster and cement trowels and floats made by Nicholls Manufacturing Co. of Ottumwa, Iowa, USA. I have been unable to learn when Nicholls went out of business, but it was still advertising in "Popular Mechanics" in 1956. In the 1930 US Census, the occupation of Fred Hardsocg (1882-1967) was manager, square factory. In 1940 his occupation was manager, mining equipment.

"The following is from the book 'Ottumwa: Yesterday and Today' published in 1923.

"The Nicholls Manufacturing Company, 401 to 405 West Main Street [elevated street and vacant lots], with an annual production of 55,000 framing and carpenters' squares, is one of five factories in the United States which makes squares and the only one west of New England according to Fred Hardsocg, owner and manager.

"In 1901 four men formed a partnership for manufacture of a framing square on which Moses Nicholls, a carpenter, had secured a patent. The four men were Mr. Nicholls, Martin Hardsocg, T.F. Norfolk, and A. Wheeler. Martin Hardsocg purchased first the share of Mr. Wheeler and later that of Mr. Nicholls, and Fred Hardsocg, his son, purchased the interests of Mr. Norfolk. Later he bought the remainder of the holdings from his father and has been managing the business for about ten years.

"The plant is operating at capacity and is unable to meet the demand. In addition to squares the Nicholls Manufacturing Company produces floor scrapers, wood pullers, and grass hooks. When the company was established it was a real pioneer in the West and in order to obtain the expert workmanship desired Joseph Miller, an Eastern mechanic, was employed to come here. He made the first square and is still with the firm."
