the  Sörbo  scraper is the best on earth !!!!!!!!. get it you will love it ....  i recommend  the normal  blue  handled  one

it does  not  pivot  .. i have the pivoted one....  i guess this  for  pole work ??   the reason i said about the blue  one s  that it is fixed and this  will create  more secure and better strokes when  scraping... get the pivot  ..its the same  really. i just feel that with it fixed it will operate  more securely and better..

it can be screwed up tightly. but mine has  kind of siezed up at a slight angle..

this  is  a great scraper. it easy  to change  blades.  just make sure it goes into the holder when your  not using it. use triumph 6 " blades on it.   25   for  12 pound i think from WCW ( window cleaning warehouse)  its works  so well because  more blade is  hanging out and it  molds  to the shape of the glass surface . it flows when its scraping  hold it like a table tennis  player  " pen style "  go to  You tube and see Sörbo  scraper.

The angled triumph has saved my bacon on a few jobs, it's really for difficult to reach windows, but not available in the UK. I hate covers, they are too time consuming so the ZX80 works best for me. Never tried the Sörbo scraper - can't comment. When I enquired about it, something put me off, can't remember if it was the weight, the blades or something else 

I dont scrape a lot but have often cleaned windows on houses that need all the windows scraped.
I think it is about time I marketed this.

 Mr  sörbo himself said that  all or most 6 " blades will fit in the sörbo . so i bought triumph from WCW  and yes they  fitted and worked  excellent.  only  problem is they  Triumph  claim they are stainless steel..   but if  you get them  moist damp wet  they  do rust  so keep them in a dry  place

ive  had  the sörbo roughly  2 years  now. no rust on the channel holder karlos... the  unique thing  about the sörbo is the stability of it and the design of the way the blade sits in holding channel.. the blade is sticking out 2-3  times  more than any  other  scraper  and this allows the blade  to mold  to the glass  and  one feels  very safe when scraping with it . it is highly  efficient  and i have used it   many  many  times and cant speak highly enough  about this  scraper.

just like yourself    . if your in window cleaning or any job for the long run and want to be  efficient  you have  to fork money out  to  test equipment...  because hearing seeing and doing are all different  things..  the triumph definitely has its  advantages and   so has   the Sörbo  ..  it would be wise  probably  to buy  both....  it all depends  how often you scrape.. i would rather lose 15 quid  testing a  tool rather than  losing 300  scraper  hours  using the wrong scraper over the next  5 - 10 years  or any tool for that matter

sörbo has his  own holder... the  inside where the sharp side of the blade  sits  is made out of  brass. ( or similar  metal i think its  brass )...  so in effect its much safer  than a plastic  holder  !!.
