Could anyone advise me were I can buy a pair of long handled wooden grass shears been looking but no joy .
Have you looked at the Joseph Bentley range of tools?
Yes its the long handled grass shears I have seen the border ones but not the grass ones they are all plastic ones .
I'm with you now, the long handled grass shears you can stand up to cut the grass with?
I haven't seen them with wooden handles for years. Perhaps someone else can find some on the net, I would buy them too!
Do you mean edging shears? In 2012 Garden News decreed that Burgon & Ball's wooden handled edging shears were the Best Buy http://www.burgonandball.com/press-room/media/uploads/Garden%20News%20Lawn%20Edging.pdf , but I can't find any in their catalogue https://www.burgonandball.com/media/bb-2014-catalogue-low-res.pdf . Perhaps you could contact them and see if they still have any in stock?
Otherwise I suggest that attending a rural auctioneer's regular deadstock auction, where they often sell gardening equipment from house clearances etc, may turn up what you're looking for
I go to my local scrap yard to pick up wood handled tools. I get some seriously nice stuff for peanuts. Shears can always be oiled, sharpened and tightened up. I much prefer to work with wooden handles, plastic ones make my hands ache.
