How to Sharpen Tools Using a Flashlight. Bricolez Une Guide D'affutage. Bricolaje Una Guia De Afilado




About: I am an escapee from modern life, now living by the sea in a forest garden in France. After over 20 years industrial experience, I quit my managerial position to study for a degree in Engineering. That done ...

Chisels and planes come from the manufacturer with a 25 degree bevel and you are expected to home this to 30 degrees. Here's how I do this with basic geometry and without the use of an expensive honing guide.
If you prefer, there is also a two-part  blogpost at:  and

Comment aiguiser les outils à l'aide d'une lampe de poche. Ciseaux et des rabots viennent de l'usine avec un biseau de 25 degrés et devrait être perfectionnée par vous à 30 degrés. C'est ainsi que je le fais avec la géométrie de base et sans l'utilisation d'un guide d'affûtage cher.

Cómo afilar herramientas con una linterna. Cinceles y aviones vienen de fábrica con un bisel de 25 grados y se espera que se perfeccionó por usted a 30 grados. Así es como yo lo hago con la geometría básica y sin el uso de una guía de afilado caro.

    Hi Rimar2000,
    You are welcome! We were thinking about you today, we saw the most amazing program about the gardens of Argentina! It is called 'Around the World in 80 Gardens' and there was an episode on South America - very beautiful and fascinating. Feliz Año Nuevo a partir de nosotros dos, Andy y Sue

    You make me feel ashamed, because I have a small garden in front of my house and one at the back, but both are quite neglected. The things I plant refuse to prosper, only the weeds seem to be comfortable. I think the ground is not very good, and I don't want to spend money on nutrients not being sure. I should hire someone who knows, but that will cost me some money.

    Dont mean to butt in,but my soil in my garden area when I started was so poor you couldnt raise a fuss on it,and what little green that was there was grab grass.My brother ran all through the space with his dirt bike,It was a mess,so I started with pretty plants that dont require real rich soil.The library was my source of info at that time,long story short,it took about twenty years,but due to leaving the leave and grass clippings to rot,as well as free mulch from our landfill because of our recycle progam,my soil is as rich as the next persons,and dont look too bad either.Quik tip,buy the cheap plants that have started looking ratty,also high dollar damaged plants gets you a big discount,and at most garden centers carry the same warranty.If you hire someone,youll cheat yourself out of doing what I know you can do.You will be proud.

    Thanks for your advices, spylock. I always discuss with my wife because she orders the boy that cut the grass, pick up grass clippings and to put them in a polythene bag on the street to be picked up by the garbage truck. I intervene when I can so that instead that he scatter it around the plants, and I see that over the years the ground is slowly improving.

    Check out the composting info here on site, and you can make fairly poor soil grow very well indeed. Conversely, try growing plants in containers for a controlled growing space and forget the poor ground altogether. You might look into simple 'raised bed' type of gardening, where simple wooden frames hold good soil up and you grow the plants in a easily worked area off the poor ground altogether. Compost can be made of many things often free for the taking if you check your area. Best of luck my friend on making those two garden spots green this year.

    We have poor soil in front of the house also, but we have chosen plants that do well in such conditions, funnily enough they are mostly from South America! Verbena bonariensis, Marvel of Peru ( Mirabilis jalapa), Geranium - Cranesbill and Nicotiana sylvestris, with the last one we just add some extra compost from our bin and you need to water this one to get a really large plant (1.5m) otherwise it will stay small, this one and the Marvel of Peru have a fabulous perfume too!!

    If you would like some seeds of the Mirabilis jalapa and the Nicotiana sylvestris we could send you some.
    That will save you some money!
    Best Wishes, Andy & Sue.

    Thanks for the offer, Andy & Sue. Beautiful these flowers. We have a Floripondio (Brugmansia), that is beautiful and with marvelous parfum, but have very bad reputation because its dangerous properties. It seems to be like Nicotiana sylvestris.

    Seriously simple and accurate system, a piece of genius applied to an often vexing shop task. Well done indeed!!!

    Who would think that the geometry (or trigonometry?) that I learned in school can help me sharpen my chisels! Yours is a great example. I used it to convince my teenage son and daughter that math will always be helpful. Thank you very much for sharing!

    Glad to be of help. On the same subject I've seen guys welding steel frames together and ensuring they are square just by using the Pythagoras theorem, good old 3 4 5 triangles never fail!
    Thanks for commenting. Best Wishes, Andy.

    Briliant !!!
    Could be used for sharpening knives too, but the shorter width of the blade would make it harder to use this method
