Hi guys, what will be the best way to do,to  have a perfect rubber cut. I used scissors myself but I dont know its still not that perfect since there are portions that are not that really on the edge of the blade sometimes in ruins the rubber itself if i over do it.
Thanks.

exacto knife for a perfect cut, but it takes 3 times to fully cut through all the rubber.

im not that picky so i just scissors and i think i do a decent job.

You can use a board, some people put duct tape on a piece of cardboard, anything that will protect good surfaces.

I find using curved craft scissors to be much easier and less complicated, no need to worry about protecting surfaces from a blade.

I use a curved scissors. Put some light oil on the scissors before you cut so that it reduces friction with the rubber.

Does a pretty good job. You can get them from hobbyist shops or get a curved manicure scissors from the ladies department. Manicure scissors are much smaller so it will take longer to cut but if you patient, you can make very nice clean cuts.

Personally i like a bit of the edge sticking out after a cut because once the glues evaporates, the rubber will shrink a little.

JH, some good tips here that many don't don't normally talk about. The oil or something to lube the rubber helps a ton. So does using a lot of tiny cuts, instead of trying to do it long and fast. You could make a nice cut from a pair of under $1 kids scissors using those two tips. I don't have the knife or the skill to make the exacto method work right.

I use just a regular pair of scissors and my cuts come out fine.  Just just short cuts.  The scissors need to be really sharp though.

try a utility knife,the small snap off blade type making sure to keep it straight or upright ,if you angle it the sponge can protude past the topsheet,the vendors at tournaments i have been to use this method,you can use a glass vegetable cutting board to rest on.

The cut doesn't really matter that much to me.. It usually ends up something like Waldner's cut:

Maybe we all should cut sloppy like Waldner to be able to play genius like him LOL

I see... the inconsistency of the sheet allows him to play some awesome balls that can may be inconsistent in terms of speed and placement, wow, he's really a geniusLOL

Seriously, I use a knife to make tiny little vertical hits all around the blade, then I finish with wet scissors, the cut will follow without any need to follow the track.

The alternative (if you can afford it of course) is to use a replaceable surgical blade, so that the only part that has to be replaced is the actuall cutting blade and not the handle as well, each blade will do approximately three bats, depending on the hardness of the timber that is used as a backing under the rubber you are cutting, before long you will notice that the blade is no longer cutting as well as it did when new, another Idea that has been proven to me is to draw a pencil line around the full circumference of the blade, whist the blade is still on the sponge make two marks on either side of where the blade meets the handle, this is for correct positioning of the sponge on the blade, make sure you cut with a good quality sharp pair of scissors, (either swedish or german make) to the outside edge of the pencil line that you have just drawn on the inside of the sponge, once this cut is finnished then apply the glue, (you will find by doing it this way, you are allowing the sponge to stretch a little bit, more than what it would do on the blade, also cutting to the outside edge of the pencil line allows a fraction more leeway, the result will be once you have both rubbers glued on you will notice that there is approximately at least a 1 mm overhanging edge between the blade and the edge of the rubber, this will save you if you accidentally hit the blade into table while pushing too close to it, also with regards to using the oil for lubrication, if you don't have any oil handy, a glass of soapy water is a good substitute.

Great post! I myself cut using a surgical blade (my dad gets them from work). Using a pencil to mark the outline would definatly help when scoring the cuts on the rubber. So thanks for that..

Here is how my cut comes out using a surgical blade:



Far from perfect but it's a much better cut than I used to get with scissors. It usually takes 3 cuts to get through inspirit with the blade.

Basically what I did is bought a pair of sharp sissors that I only use for rubber cutting.  I glue on the rubber then (in one cut) cut off the excess.  I'm really satisfied with how it comes out, very smooth. 

I think an exacto knife or surgical blade could work better though.

after pasting the rubber, flip the blade with the rubber( so the the sponge part will face u)
 
then just use a cutter (mine is just S$1), and start cutting the rubber by following the blade contour(shape). the blade will not be cut as the body of the cutter-blade is thicker than the sharp part
 
TIP:
1.use the other hand to press the TT blade firmly againest the cutting board
 
2.u will need alot of strength while cutting
 
3. press the cutter down firmly while cutting - making sure u had cut the rubber with the top sheet apart
 
4. Lastly - YOU MUST CUT THE RUBBER WITHIN 1 OR MAXIMUM 2 CUTS in order to get the cuts like mine
 
 
hope to see yor perfect cut in the near future
thx

Yup, this technique works perfectly, for hard rubbers I guess, I tried this on some lkt pro xp and the result was terrible, oh well, it may be my technique haha, but for 729 rubbers, I never got any problems getting a perfect cut with erikat method. You also need a good glue with strong bond, sometimes cutting like that may remove the bond, that's why(like erikat said) you must press very firmly.

Nice cutout, Erika.
 
And if I may add, if using a cutter, or a knife, try to cut the rubber with the cutter vertically and in 1 (max 2 cuts).

Here's the way i do it.

Originally posted by zrrbiteDK zrrbiteDK wrote:

Take a fresh razor blade - push it 3 lines out.



Press the razor, completely vertical, against the tt blade, so that the razor bends slightly. Applying both pressure inwards and downwards, you will get a smooth and clean, vertical cut.  Applying pressure in/down while pressing the blade against the tt blade, will use a larger surface of the cutting tool.






Its extremely important not only to apply pressure downwards (using only the tip of the razor), but also inwards, as you may then accidently cut under the blade with a cutting angle like this -> / , because the edge of the tt blade is too small a surface too small to provide proper guidance for the razor.   This will result in the sponge showing past the topsheet, as firetack puts it.

*edit for clarity*
