“I have numerous Terry Jacka whips in a variety of lengths, styles and handle dimensions and
they always come through for me under the pressures and performance extremes that are the norm
in live shows and on horseback where failure isn't an option. I need to be able to repeat the action
effectively and consistently. This is equally true during on-the-set film performances where you've got
80 people on salary standing around watching, and you need to get it right in the least amount of time
possible. I depend on my own skills and the quality of my equipment to keep my action partners and the
surrounding support team safe. I've been using Terry's excellent whips for well over twenty years and I
have nothing but praise and admiration for the quality and consistency of his work. He's my go-to-guy when
it’s crunch time and it absolutely, positively has to work.” - Anthony De Longis

 

Anthony De Longis, whip trainer for Harrison Ford for the movie gave the specifications for the whips to be used.
Anthony required whips in both eight ft. and ten ft. lengths, only the ten ft. whips were used for the movie

"I asked Terry to copy the dimensions of the Morgan whips that had been made in advance in preparation
for some of the planned effects. The design of the “American” style bullwhip, which is the Indy standard,
is best suited to single throws from all eight angles of attack on both the forehand and backhand sides.
However, this shorter handle makes rapid multiple throws difficult, especially when transitioning from
single throws to complex compound combinations, which I wanted to be able to incorporate into Harrison’s
whip vocabulary. I knew from my long association with Terry and his methods that he would extend the belly
of the whip during construction and give me as tight a weave as humanly possible. While the handle would
look almost identical, the stiffer extended belly would provide additional leverage to the help reform the
“loop” quickly and facilitate a wider variety of successive throws."

- Anthony De Longis

The handles on both lengths had the same dimensions.
Specifications asked for: - Handles to be the same size as the standard eight and ten ft. whips (7/8 inch dia.) with 5 inches between the two turks heads which made for a 7 inch long handle foundation. The main turks head to be about 1/3 larger than the standard straight handled eight and ten ft. whips. The weight of the ten ft. whips were averaged over four whips at close to 2 lbs. (906 gm.).

Drum stuffed saddle tan leather was used for all whips sent and the falls made from American Latigo.
