We got this one, bought in 2011 as you see, it gets a lot of hard work here, we’ve replaced the blade once, you can turn them over but not sharpen them. Will buy another blade this year probably.if you can get a good 2nd hand one it should be ok, no telling with that though, someone may be getting rid because it’s knackered.
We've got a similar looking Bosch shredder as well but maybe a bit older. it has a corkscrew effort inside which crushes the wood? Didn't know you could get replacement blades - is there one inside as well as the corkscrew bit?
Thanks Slum, I didn't think it had a cutting blade as well so that's good to have it confirmed. It doesn't cope with leafy stuff at all unfortunately. Ours must be about ten years old now. Must remember about selling spares on Ebay though.
